01:31 AM Deejay: moin
02:24 AM pink_vampire: hi
02:35 AM Loetmichel: mornin'
02:35 AM Loetmichel: hmm, anyone tried to use those waterproof led "glue on" strips for machine lighting on a CNC 6040?
02:36 AM Loetmichel: i thought of putting one strip under the gantry and another as an "u" around the walls of a housing i want to put them into -> http://www.cyrom.org/palbum/main.php?g2_view=core.DownloadItem&g2_itemId=17261
02:37 AM Loetmichel: (the red thing in that PDF is the CNC 6040, the black stuff are the wooden boards and the plexiglas)
04:19 AM XXCoder: hey pink_vampire
04:19 AM pink_vampire: hi XXCoder
04:19 AM XXCoder: whats up
04:29 AM Tom_L: morning
04:30 AM XXCoder: morning
04:33 AM Tom_L: Loetmichel, i used an under counter flourescent strip in mine but that was before led
04:34 AM Tom_L: will the adhesive withstand any coolant etc that may get splashed on it?
05:18 AM pink_vampire: https://newyork.craigslist.org/mnh/avo/d/new-york-city-need-good-man/6881757861.html
05:18 AM pink_vampire: XXCoder: ^
05:18 AM XXCoder: little bit far off lol
05:26 AM Loetmichel: Tom_L: its a CNC 6040
05:27 AM Loetmichel: no flood coolant. flower atopmizer with water and dish detergent/Isopropanol at best
05:27 AM Loetmichel: -p
05:28 AM Loetmichel: also: the enclosure will be made of "siebdruckplatte" ( marine plywood with one glossy side and one sieve imprinted side )
05:29 AM Loetmichel: so while that stuff is pretty resilient to water it is STILL wood
05:47 AM jthornton: morning
05:47 AM XXCoder: hey
05:55 AM jthornton: I used to use photobucket.com a long time ago but now they are charging and I can't even delete the photos that I have on there lol
05:56 AM XXCoder: geez lol
05:56 AM jthornton: every 10 seconds or so they want to send a conformation to your email lol
06:08 AM Loetmichel: maaan... forgot to choose a frozen ready to eat menue for heating up for lunch again... now coworkers do lunch and i sit here with Military rations buscuits and choclate :-(
06:08 AM XXCoder: lol never a problem for me
06:09 AM XXCoder: in rare cases i run out of soylent i just use vend
06:10 AM Loetmichel: (good thing i bought those rations though... comes in handy these times when i get forgetful :)
06:10 AM XXCoder: i have enough soylent at shop to last me entire month ;)
06:11 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=15627 <- left to right: canned bread (already empty), biscuits, chocolate, and in front the "exotic fruit" drink powder
06:12 AM XXCoder: fancy
06:14 AM Loetmichel: expensive. but best before around 2050 ;)
06:14 AM XXCoder: indeed
06:36 AM XXCoder: amazing
06:36 AM XXCoder: https://www.youtube.com/watch?v=y0iNp5VgFfk
06:36 AM XXCoder: resin and charcoal
06:37 AM SpeedEvil: That was neat.
06:38 AM SpeedEvil: Though i suspect he'd have somewhat better results if he evacuated the air, then dropped the charcoal into the liquid.
06:38 AM SpeedEvil: Rather than trying to pull air through a surface sticking layer of liquid.
11:07 AM * Lcvette uploaded an image: corner_probe_equation.png (47KB) < https://matrix.org/_matrix/media/v1/download/matrix.org/drUQtWLDAJvYmvoTCYFQVJRI >
11:07 AM Lcvette: need a formula for this
11:11 AM cpresser: Lcvette: one way to do it: create two linear functions, one for the line with P2 and P3 on it; one for the line with P1 on it
11:12 AM cpresser: put those two functions into one equation and solve for x; then put that x into any of the functions to get y
11:14 AM Lcvette: cpresser: im many years out of school
11:15 AM Lcvette: and those functions are long forgotten from lack of use
11:15 AM Lcvette: the ones i use daily are easy to remember, but the ones i haven't seen in 25+years are harder for me
11:15 AM Lcvette: lol
11:23 AM Loetmichel: MAAAN now i am pissed at BMW. Tried to re"iron" the foil cable on the BMW E39s odometer display... result: 5 of 5 instrument shafts pulled out of the drives WITH the springs (wenn pulling the hands)... 150eur for a new used instrument cluster ... and now driving with the tachometer/odometer on the android radio... :-(
11:35 AM Loetmichel: ... at least i HAVE an android radio, so "there is an app for that"... wouldnt be so good to drive without a speedo. its mandatory in germany. :-)
12:23 PM rmu: Lcvette: 2 or 3 dimensions?
12:24 PM Lcvette: 2
12:25 PM Rab: Loetmichel, Autobahnpolizei will accept an Android app?
12:25 PM Lcvette: these are the variables as written in the probing routine
12:25 PM Loetmichel: Rab: no idea
12:25 PM * Lcvette sent a long message: < https://matrix.org/_matrix/media/v1/download/matrix.org/UrAbXjNaBMGFFhHtDHpGzzNx >
12:26 PM Loetmichel: but at least i know when i exceed the speed limit BEFORE i hit the speed trap
12:26 PM Loetmichel: meaning i can drive in the "allowed zone"
12:26 PM Loetmichel: without a speedometer i doubt i would nail that 50kmh in citys
12:26 PM Lcvette: rmu: the probing routine will supply all variables except c1x and c1y which is what im trying to make an expression to solve for.
12:28 PM rmu: i'm just having dinner, give me a minute
12:32 PM rmu: Lcvette: it shouldn't be that complicated. let nx be p2x - p3x, ny be p2y - p3y, nx0 = nx / sqrt(nx^2+ny^2), ditto for ny0
12:32 PM Lcvette: rmu: below is the probe routine if it is helpful, it calls on other subs for the primary probing as can be seen which return the values shows that become the probed points for the expression needed for P1, P2, P3
12:32 PM * Lcvette sent a long message: < https://matrix.org/_matrix/media/v1/download/matrix.org/ZUQlkjCRTPDrshziVQfZrXwN >
12:34 PM rmu: then the distance between p1 and c1 should be n0x * p1x + n1y * p1y - n0x * p2x - n0y * p2y
12:34 PM rmu: and coordinates of that point should be p1x + d * n0y and p1y - d * n0x
12:35 PM rmu: sign of d may be wrong
12:36 PM rmu: hmm
12:37 PM rmu: wrong
12:37 PM rmu: nx = p3y - p2y, ny = p2x - p3x
12:38 PM Lcvette: are you trying for the slopes?
12:38 PM Lcvette: i have those in the routine already
12:40 PM rmu: don't understand
12:41 PM Lcvette: me either
12:41 PM rmu: 1) you calculate the vector perpendicular to P2P3
12:41 PM rmu: (n)
12:41 PM Lcvette: sorry wrong calc
12:41 PM Lcvette: that looked like the edge angle calc
12:41 PM rmu: 2) you make this vector length 1
12:42 PM rmu: = n0
12:43 PM rmu: n0 * (x y) = n0 P1
12:43 PM rmu: sorry
12:43 PM rmu: this is easier with an actual chalk board
12:43 PM Lcvette: lol
12:43 PM Lcvette: no worries
12:43 PM rmu: that should be n0 * (x y) = n0 P2 (or P3, doesnt matter)
12:44 PM rmu: tah gives an function of x, y like f(x,y) = x * n0x + y * n0y - n0x * p2x - n0y * p2y
12:45 PM rmu: then you calculate f(p1x, p1y), that is the distance of point p1 from the line through p2 / p3
12:46 PM rmu: point C is therefore n0 times f(p1x, p1y) + p1
12:49 PM Lcvette: thats a big equation
12:53 PM rmu: no
12:53 PM Lcvette: i was looking into possibly rotating P1 and P2 around Z1 by the edge angle to give me c1x,y then rotating c1xy back
12:53 PM rmu: c1x = p1x + d * n0y
12:53 PM rmu: c1y = p1y - d * n0x
12:54 PM rmu: d = n0x * p1x + n1y * p1y - n0x * p2x - n0y * p2y
12:54 PM rmu: nx = p3y - p2y, ny = p2x - p3x
12:54 PM rmu: nx0 = nx / sqrt(nx^2+ny^2), ditto for ny0
12:54 PM rmu: thats all
12:55 PM Lcvette: right, but i have to define every variable
12:55 PM Lcvette: in the ngc
12:55 PM Lcvette: or it has no idea what it is
12:55 PM Lcvette: so it becomes a monster
12:56 PM rmu: don't unterstand the problem. so you have 6 lines like #<_nx> = [#<p3y>-#<p2y>]
12:57 PM rmu: #<_ny> = [#<p2x>-<p3x>]
12:57 PM Lcvette: ok
12:57 PM rmu: #<_nl> = [sqrt[#<_nx>*#<_nx> + #<_ny>*#<_ny>] ]
12:57 PM rmu: and so on
12:58 PM Lcvette: let plug it in and see if i can make it kick out what we need
12:58 PM rmu: don't know if sqrt is legit
12:58 PM rmu: maybe the sign of the n vector is wrong in my calc
12:59 PM Lcvette: http://linuxcnc.org/docs/html/gcode/overview.html#gcode:functions
12:59 PM Lcvette: functions for ngc
12:59 PM Lcvette: SQRT is correct
12:59 PM Lcvette: SQRT[arg}
12:59 PM Lcvette: ]
01:00 PM Lcvette: #<d> = ?
01:03 PM Tom_L: how can you find X Y of C1 if nothing is fixed?
01:04 PM Lcvette: it will be
01:04 PM Lcvette: the subroutine defines the parameters
01:05 PM Lcvette: ie edge_width is given a user input such as 1.5"
01:05 PM Tom_L: my kid had to do something similar at his Skills competetion last year when he hand wrote gcode for a given part
01:06 PM Tom_L: had to figure arc centers and tool offset etc for several things
01:06 PM Lcvette: then when the subroutine is run, the probed points define (p1x, p1y) (p2x, p2y) (p3x, P3y)
01:07 PM Tom_L: but you still don't know the distance to C1 from P1 or P2
01:08 PM Lcvette: thats the formula we are hashing out
01:08 PM Lcvette: there are a few ways to get there
01:08 PM Tom_L: 2 points on one side
01:08 PM Tom_L: will give you a vector
01:08 PM Lcvette: with the given data set
01:09 PM Tom_L: and the angle then P2 would be the other point of the hypotenuse
01:09 PM Lcvette: correct
01:09 PM Tom_L: but 2 points on the p1 side would give you the orientation
01:10 PM Tom_L: like you did with P2 P3
01:11 PM Lcvette: well with 1 point and the slop you can create a line
01:11 PM Lcvette: slope
01:12 PM Lcvette: so you can have P1 and a formula that defines other points on the same line
01:12 PM Tom_L: are P1 P3 in the same Y plane?
01:12 PM rmu: Lcvette: d is the distance from p1 to the line trough p2/p3
01:12 PM rmu: everything is in one plane
01:12 PM Lcvette: or for example the most basic would be to use the slopes rise and run added to the P1 coordinates to give a second point
01:12 PM rmu: z=const
01:13 PM rmu: 19:50 < rmu> d = n0x * p1x + n1y * p1y - n0x * p2x - n0y * p2y
01:15 PM Lcvette: will i need to define n0x, n1x, n0y, n1y etc too?
01:15 PM Lcvette: i suspect it isn't going to recognize them
01:16 PM Lcvette: rmu?
01:17 PM rmu: typo
01:17 PM rmu: n0y
01:17 PM rmu: d = n0x * p1x + n0y * p1y - n0x * p2x - n0y * p2y
01:18 PM Lcvette: crap, need run and get some orders togethe rfor piuckup
01:18 PM Lcvette: back in a bit
01:19 PM Lcvette: will woprk on it more this evening
01:28 PM miss0r2: upgraded circuit diagram for the TB6600
01:28 PM miss0r2: https://xkcd.com/730/
01:32 PM rmu: Lcvette: you just have to copy/paste it into your probe script
01:45 PM gloops: .
01:45 PM gloops: https://www.ebay.co.uk/itm/Berger-Lahr-SER3913-4L3SS0TO-Servo-motor-not-closed-loop-stepper/143242518757?
01:47 PM rmu: Lcvette: https://imgur.com/a/QYdABnh hope i didn't make too many typos ;)
02:21 PM Lcvette: rmu: back
02:30 PM rmu: Lcvette: https://imgur.com/a/QYdABnh hope i didn't make too many typos ;)
02:54 PM Lcvette: was just getting dinner started now im trying to get this put in again
02:57 PM jym: Lcvette: When all else fails, grab a bigger hammer
02:57 PM Lcvette: hahahaha
02:58 PM Lcvette: this expression will finish the last 4 subroutines needed for the probing page
02:59 PM Lcvette: they are probe routine numbers 37-40
02:59 PM Lcvette: needless to say my eyes are crossed by now
02:59 PM gregcnc: ugghh anyone mess with ide flash drives in old mobos?
02:59 PM DaViruz: a little
03:00 PM jthornton: I have one on the 386 motherboard that runs the BP 308
03:00 PM gregcnc: I have a drive that seems to be cloned properly, but it hangs at DMI verify
03:01 PM jym: gregcnc: Did you set the drive to "auto" in the bios?
03:01 PM gregcnc: yes
03:01 PM jym: gregcnc: what size drive is it?
03:01 PM gregcnc: 8gb
03:01 PM jthornton: I have to set the cyls and heads on mine or it won't boot
03:01 PM gregcnc: replacing a 10gb hdd
03:01 PM jym: Yeah, what jthornton said
03:02 PM DaViruz: gregcnc: what's the next step?
03:02 PM DaViruz: i'm guessing boot
03:02 PM jthornton: but mine is on a 386! and it's 256k
03:02 PM jym: gregcnc: did you clone the drive?
03:02 PM gregcnc: i've done CF adapters the same way
03:02 PM jym: on THIS mobo?//
03:03 PM gregcnc: it's a process, clone, resize to 8gb, image, restore
03:03 PM gregcnc: not thi mobo
03:03 PM gregcnc: this drive did try to boot in a newer mobo
03:03 PM jym: and you cloned the MBR too?
03:04 PM gregcnc: i think so
03:04 PM gregcnc: using clonezilla
03:04 PM jym: IS the old drive still good?/
03:04 PM gregcnc: yes
03:05 PM gregcnc: I did try this mobo with a ide-> sata and 8gb ssd, it started but performed poorly
03:05 PM jym: First, I'd check the bios setting if you think the cloning went well. Set manually and see if that helps.
03:06 PM jym: Secondly, you CAN verify the MBR between the two drives if you like
03:06 PM gregcnc: how to determine settings?
03:07 PM gregcnc: I looked at what the other mobo atuodetected, use that?
03:07 PM jym: Depending onthe drive, you can look on the label or google for cyl/heads/sectors
03:07 PM gregcnc: yeah no luck
03:08 PM jym: auto used to be hit or miss back then
03:09 PM jym: whats the model# of the new drive?//
03:10 PM gregcnc: ebay buy, d6101 8gb p/n cp1v40ma1710-008
03:12 PM jym: So it's NOT a hdd, but a DOM ???
03:12 PM gregcnc: yes (i asked about ide flash drives
03:13 PM jym: All I saw was IDE and drives =) Ok, is this the ONLY device on the cable?
03:13 PM gregcnc: plug directly to mobo
03:14 PM gregcnc: recongized in bios
03:14 PM jym: Ok, is there a jumper or setting to say it's primary or seconday, master or slave in the bios?
03:14 PM gregcnc: there is a switch on the dom, if switch it doesn't show at all
03:15 PM jym: So what does the biod identify it as when powering on?
03:15 PM gregcnc: it shows up as primary 7.9gb
03:16 PM jym: and you are using linux?
03:16 PM gregcnc: no
03:16 PM jym: what are you using?
03:16 PM gregcnc: w98
03:18 PM gregcnc: I have 2 linuxcnc running from CF and IDE. i have a similar w98 running from CF. not sure what's going on here, but i'm not a computer dr.
03:20 PM jym: Dumb question, but did you apply power to the DOM ?
03:22 PM gregcnc: yes. I saw the splash screen on another mobo, but it can't actually boot on that
03:22 PM gregcnc: probably just a compatibility issue
03:22 PM jym: Do you have a W98 boot diskette?
03:23 PM gregcnc: yes
03:23 PM jym: Try formatting the DOM (yes, this will erase the closing you did, but you'll have a chance to see if it actually works)
03:24 PM jym: format c: /u/s/q
03:24 PM gregcnc: oh, works w/ that mobo
03:24 PM gregcnc: ok
03:24 PM jym: the switches I gave are: unconditional, system (make it bootable) and quick
03:25 PM jym: That's assuming the is no ohter drive plugged into the mobo
03:25 PM gregcnc: got it
03:26 PM Rab: Formatting on the target machine is a good idea.
03:26 PM jym: The unconditional will make sure nothing is (per se) "hidden" or left over
03:27 PM Rab: Actually, I guess you want to create a partition with DOS fdisk first.
03:27 PM jym: Rab: Eh, if his clone worked, it "should" be there =)
03:28 PM Rab: jym, right, but maybe not on the CHS boundaries the motherboard wants.
03:29 PM jym: Rab: Eh, true. FDISK wouldn't be a bad idea, should also wipe any other partitions that might exists
03:30 PM Rab: gregcnc, what's the OS you're copying to the drive?
03:30 PM jym: Rab: W98
03:30 PM Rab: ahh
03:31 PM jym: I'm just wondering if FAT16 or 32
03:31 PM jym: And whoch verson of W98... a b c or d
03:32 PM jym: I'd drop w98 in favor of xp personally
04:04 PM Deejay: gn8
04:27 PM _unreal_: lot of lighting going on
04:36 PM gregcnc: jym it won't even pass DMI after accessing the floppy to boot if the DOm is plugged in
04:40 PM gregcnc: free lathe https://chicago.craigslist.org/wcl/hvo/d/elgin-cnc-lathe-warner-sawsey/6883496820.html
04:42 PM gregcnc: it's pizza time
04:45 PM JT-Shop: be right over
04:45 PM * JT-Shop goes to make salad for the chickens
04:46 PM Lcvette: rmu: i finished what i was working on before hand to test out, what do you think of this method?
04:46 PM * Lcvette sent a long message: < https://matrix.org/_matrix/media/v1/download/matrix.org/ajuOrhGySUIFIJdzsvTsqRXh >
04:54 PM * Lcvette uploaded an image: Screenshot_2019-05-07_17-50-00.png (8KB) < https://matrix.org/_matrix/media/v1/download/matrix.org/CbDQycpoagZgYCMTPREJWBqM >
04:55 PM Lcvette: this is the probing result with the offset of the tool set to zero, and it appears to form a right angle in the correct location so I am going to assume it is correct
04:55 PM Lcvette: \o/
04:55 PM Lcvette: Hurray!
04:58 PM _unreal_: gregcnc, WHOLY FARK THATS a big boy
05:03 PM rmu: Lcvette: you don't need sin/cos/atan for this case, but if it works and atan doesn't do anything stupid for very small values of edge_delta... why not
05:06 PM Lcvette: ATAN is used to find the edge angle which is the angle of rotation
05:07 PM Lcvette: rmu: what would it do stupid?
05:07 PM jesseg: Wow... I wish I had a place to put it and a way to get it there :P
05:08 PM rmu: yeah as i said you don't need atan for calculating coordinates of the point, simple vector math is sufficient like i posted here https://imgur.com/a/QYdABnh
05:08 PM rmu: Lcvette: it could be inaccurate ;)
05:09 PM Lcvette: the rotation angle is the main item we are after, the point is for locating a corner of a part with a rotated 90 degree edge
05:10 PM Lcvette: im not super familiar with ATAN as i don't use it much, but how would you calculate the rotation angle without it?
05:10 PM rmu: i thought you are interested in the coordinates of the corner, not the angle
05:11 PM Lcvette: i was because i already had the angle
05:11 PM rmu: to calculate the coordinates you don't need the angle
05:11 PM Lcvette: but the point of the edge angle probing routines are ultimately about getting a correct rotation offset
05:12 PM Lee_: Fedex won't pick up that lathe for me ;(
05:12 PM Lcvette: ie a rotation in the work coordinate system
05:12 PM rmu: ok, then you need an angle
05:12 PM Lee_: usps says they don't have a flat rate box large enough
05:13 PM gregcnc: well dang it looks like that DOM is dead now
05:13 PM Lcvette: but i am getting that angle using ATAN and now you are saying its not accurate
05:13 PM rmu: then edge_width should be large-ish
05:13 PM Lcvette: if that is the case its not worth a hoot
05:14 PM rmu: no, i didn't mean to imply it is not accurate, only that it should be checked ;)
05:14 PM Lcvette: edge_width is user defined based on the available edge of the work or work holding edge surface to probe
05:15 PM Lcvette: so if you have a 20" long edge you can put 19.5" in for the edge_width
05:15 PM Lcvette: or there abouts
05:16 PM Lcvette: but if you have a 3" x 3" work piece obviously you would put something closer to 2.8"
05:16 PM Lcvette: I can define that in the help section to use the max edge_width for highest degree of accuracy
05:16 PM rmu: it would be stupid to use 1/4" with a piece 20" long, that would result in inaccurate angles
05:16 PM Lcvette: i see what you mean now though
05:18 PM Lcvette: i thought you were saying there was an inherant flaw in using ATAN itself i was unaware of
05:18 PM Lcvette: lol
05:20 PM gregcnc: maybe a bit smaller for a little more than free https://greenbay.craigslist.org/hvo/d/bonduel-cnc-lathe/6883484394.html
05:43 PM Tom_L: rmu, if the instruments are accurate it shouldn't matter ( i get what you're saying )
06:01 PM gregcnc: jym it turns out the boot disk I made was funky. I excavated one and DOM formatted on the target pc
06:02 PM Tom_L: gregcnc, what os?
06:02 PM gregcnc: w98
06:02 PM Tom_L: 2nd?
06:03 PM gregcnc: i believe
06:03 PM gregcnc: yes
06:03 PM Tom_L: iirc i still have that in the wrapper
06:04 PM gregcnc: trying to clone os from ancient 10gb hdd to 8gb DOM
06:04 PM Tom_L: using?
06:04 PM gregcnc: clonezilla
06:04 PM Tom_L: i use ghost on the old stuff
06:05 PM Tom_L: i've never used clonezilla but i'm sure it works good
06:05 PM Tom_L: i like filezilla
06:05 PM gregcnc: I've done this a couple times, and now can't remember the exact procedure I used last
06:06 PM gregcnc: well those were CF
06:06 PM Tom_L: i _might_ have an iso of it but i can't get to it right now
06:07 PM gregcnc: problem is I don't have disks for all the apps
06:07 PM Tom_L: ahh yeah
06:07 PM gregcnc: i have the w98se cd
06:08 PM gregcnc: i need to understand MBR better
06:08 PM gregcnc: at least the compressor I got is working
06:09 PM Tom_L: i haven't run 98 for quite a while
06:10 PM Tom_L: i'm still using NT4 on one
06:10 PM gregcnc: Is desiccant an effective means of keeping boards dry in the machine cabinet?
06:10 PM Tom_L: until they get saturated
06:10 PM Tom_L: then you can bake em i think
06:10 PM gregcnc: lathe acted up again, and I think humidity is getting to the boards
06:11 PM gregcnc: ran the dehumidifier since yesterday with the door open and it woke up today
06:12 PM gregcnc: I wonder how long a 1lb would last before needing drying? 15$ for indicating at mcmaster
06:12 PM SpeedEvil: On the topic of hydraulics. https://imgur.com/gallery/E6310Uf
06:12 PM Tom_L: depends on the RH in your area i'm sure
06:13 PM SpeedEvil: gregcnc: heating the cabinet 10C reduces the humidity to a maximum of 50%
06:13 PM SpeedEvil: Or so.
06:13 PM Tom_L: SpeedEvil that guy was running the wrong way
06:14 PM gregcnc: the cabinet runs fairly warm, i think it's the cooling that causes trouble
06:14 PM gregcnc: I dont' leave it on all the time
06:14 PM sync: at least it is not skydrol SpeedEvil
06:16 PM jym: gregcnc: ok, cool
06:17 PM Tom_L: if it's a persistent problem you could put an air dryer on the inlet
06:17 PM gregcnc: no venting
06:18 PM gregcnc: jym what next?
06:18 PM SpeedEvil: Unless it's well sealed, the dessicant may do little
06:19 PM jym: gregcnc: Rab suggested using FDISK to clear any existing partitons and create a new on
06:19 PM gregcnc: this happened a year ago, just before I got AC for the garage
06:30 PM Tom_L: you need to recover the boot record?
06:31 PM Tom_L: fdisk usually works
06:32 PM Tom_L: i had grub on one i had to physically write raw data to the disk to clear it
06:32 PM Tom_L: 0000 or FFFF i forget which
06:33 PM Tom_itx: dd if=/dev/zero of=/dev/sdX bs=1M *replace X with the target drive letter.
06:34 PM Tom_L: mind you i didn't let it run all the way thru, just enough to get past the boot record
06:35 PM Tom_L: ( don't try this at home ) unless you know what it's gonna do
06:35 PM tiwake: Tom_itx: there is a faster way with the cp command
06:35 PM tiwake: I forgot what it was though
06:35 PM Tom_L: it was pretty quick. i only did a couple sectors
06:36 PM jym: Tom_ This isn't recovering the MBR, it's verfying the DOM works in the new mobo
06:37 PM gregcnc: all seems ok so now I need to get the image onto the drive
06:38 PM jym: gregcnc: Does the DOM boot to a dos promtp now?
06:40 PM jym: gregcnc: ...that is, no floppy in the drive and not booting from any over drive/device except the DOM
06:41 PM gregcnc: it does
06:41 PM jym: gregcnc: dir /ah
06:42 PM jym: gregcnc: how many files does it show when you enter that command?
06:43 PM gregcnc: 4
06:43 PM jym: io.sys system.something command,com and ???
06:44 PM gregcnc: io, msdos, drvspace, bootlog
06:44 PM jym: OH GAWD
06:44 PM gregcnc: wrong disk?
06:44 PM jym: gregcnc: VER<enter>
06:45 PM jym: Nah, just that DRVSPACE is an annoyance
06:46 PM gregcnc: 98 4.10.2222
06:46 PM jym: Eh, it should be fine
06:47 PM jym: gregcnc: what size DOM (c partition) does it report?
06:47 PM gregcnc: 7534.89MB
06:47 PM gregcnc: available
06:48 PM gregcnc: wait
06:48 PM jym: gregcnc: That's 7.5GB that's fine.
06:49 PM jym: gregcnc: Ok, you've verified that you mobo sees and is able to boot fromt he DOM and reports 7.5GB so you can try doing your imaging now =)
06:50 PM gregcnc: ok
06:50 PM jym: gregcnc: You might want to make sure your image in 7.5GB or smaller
06:51 PM jym: is*
06:53 PM gregcnc: right, I did that first time around. clonezilla errs if there isn't room though
06:54 PM jym: gregcnc: Musprhy's law says you'll notice it's too big when you've gotten to 99.99999% completed restoring theimage =)
