Problem report:
(This is not a bug report. I believe the Slackware code is OK. I need
to know what I'm doing wrong, or if what I am doing is doable):
Hardware:
GigaByte GA-586ID dual Pentium mainboard
Generic NCR53C810 SCSI/PCI card.
Fujitsu M2915S-512 SCSI HDD
Software:
Slackware 2.1/2.3 (will explain)
Problem on installation:

Boot from Slackware 2.1 stock SCSI 1.44 boot disk:

OK. So far, so good. However, when I enter fdisk to a partition setup,
fdisk reports that /dev/sda has 1023 cylinders, 67 heads, and 62
sectors. (the Fujitsu has 3012 cylinders, 15 heads, and 89 sectors). The
system will install and boot as long as I set up the disk as One Giant
Partition, and add a LILO boot option of:
hd=3012,15,89
Any other combinations I've tried result in failure. (And this one
doesn't work very well).
Has anyone had experience with this or a similar problem? I frankly
suspect the problem is with the mainboard (a very new and exotic device),
but have no way to verify this. Is there a solution? I have source,
and am willing to try a custom-built kernel if it will help solve the
problem.
