[comp.unix.i386] HELP: Can boot UNIX from HD, CANNOT Boot DOS from Floppy

brr@abcom.ATT.COM (Rao) (08/27/90)

When I try to boot DOS (3.2) from my Floppy Drive (SCSI bus),
I get a Disk Boot Error, and the 5-1/4 in 1.2 M
Floppy spins uselessly.

However, I am able to boot ISC UNIX from the HD (SCSI,
Adaptec Controller). 

The  problem started when a friend CTRL-ALT-DeL when he was 
in the Diagnostic Mode, performing some Diag tests.

Please let me know how I can cure this.

Do I have to change the BIOS on the motherboard?

power cycle the machine, go into setup mode and verify that the machine
is configured correctly (pay special attention to the configuration of
the floppy disk).  Then smash your friends fingers with a hammer.

I have even seen instances of under the AMI bios you need to take power off
the cmos (external batt. or onboard nicad) and let it discharge before you
can unscramble the cmos setup.

On the newer AMI revisions you can hold down <INS> while booting and CMOS
is ignored. The leaves you with (conservative) parameters and usually gets
things running.
