i just received my minix 1.5 and want to backup the disks. does anyone know what to use to backup the disk if they are not ms-dos compatible? also, are they 720 or 1.44? also later i want to install minix on an ibm 55sx and a northgate 486? has anyone already done this and have comments. would appreciate the help.

It took about an hour to write in Turbo Pascal. Avoid the MS-DOS interface and go straight to the bios and its all a piece of cake. If I remember correctly the stack pointer is destroyed so you have to save and restore it. Hope that this is of some use. Regards Michael Salmon

The disks we got were not formatted on all 80 tracks, therefore the standard ms-dos diskcopy would not work. Also, the boot block on the boot disks makes it uncopyable with diskcopy. However, if you have a 2 drive system and you boot Minix you can copy entire disks with cp /dev/fd0 /dev/fd1 I got error messages when Minix read the last formatted track on the source disks, but the copies are still usable. Uh, yeah, you still have to format the destination disk with MS-DOS. Brian.Wilson@Sonoma.EDU

I use PC-dos 3.30 and never had any problems copying non-dos disks with diskcopy. I believe that is a problem with MS-dos only.

Also, the boot block on the boot >disks makes it uncopyable with diskcopy. I've seen others complaining of being unable to diskcopy the Minix disks. I've never had a problem doing DISKCOPY A: A: under PCDOS 3.30 on serveral machines. I copied all the 1.2 and 1.3 distributions this way. Although I assume the disks I received were formatted on all tracks since DISKCOPY read all of them fine. Just curious as to what problems others have had in this regard. gchamby%cs-col

You might be interested to know that DOS 3.3 DISKCOPY works OK; but *only* if it is PC-DOS! Unusual to find IBM being less stringent than MS! Anyway, if you have PC-DOS then DISKCOPY should work... -------------------------+------------------------------------------------- Bob Eager | University of Kent at Canterbury | +44 227 764000 ext 7589 -------------------------+-------------------------------------------------

I also had the problem of how to backup the Minix disks. I had the PH 1.5 distribution on 3.5" floppies. Left to its own devices diskcopy on my Zenith assumed that the disks were only 40 tracks apiece. (This was the side effect of the non-MSDOS format it found when looking at the disks). I ended up writing a fairly crude program that used the INT13 interface to read the originals and write out a copy. - A side effect I had was that I had to do a 'dir' on a standard DOS 720k disk before running my program. I assume that this was to do with the auto density/type detection code in the standard BIOS drivers. I imagine the differing replies here depend on whether people were copying 360k disks in 360k drives, 360k disks in 1.2M drives, 720k disks in 720k drives, or 720k disks in 1.4M drives!
