[comp.os.minix] laptop compatibility

dprrhb@inetg1.Arco.Com (Reginald H. Beardsley) (12/15/90)

I brought Minix 1.5.0 (P-H distribution)  up on a Compaq LTE/286 last weekend and everything tests 
ok.  I had access to a 5.25" drive and loaded the system  from the P-H disks.  I was able to make
backups of some of the disks using another machine with MKS toolkit on it (a great product by the
way!)  I used the following sequence:
1) dd if=a: of=<disk n>
2) dd if=<disk n> of=a:
I was not able to do all the disks like this but that was because the a: drive was a 1.2MB unit and 
began refusing to format the floppies.  I did successfully copy the root file system this way, and
if memory serves me, the boot floppy also.
NB:  Minix from P-H will NOT boot from a 1.44 MB floppy.  The problem is in /usr/src/tools/bootblok.s
which will not handle 1.44MB disks.  I covered the sense hole on a 1.44 disk and formatted to 720KB
and then built a new boot floppy with the makefile in /usr/src/tools.  If any one has a patch for 
bootblok.s and /or information on booting from the hard disk please post it, send it to me e-mail , 
or tell me where I can pick it up via anonymous ftp.  Thanks.
