I've put together a machine from some parts lying around. Not the most
recent ones. Most notably a 75 MHz Pentium (clocked at 90) on an Intel 
Plato MB.  The disk is a somewhat more recent Quantum EL 5.1 Fireball.

This disk has several layouts:

cyl's hds sec mode
10602  15  63 NORMAL
  623 255  63 LBA
  662 240  63 LARGE

I installed 3.3 using FTP with the BIOS set to LARGE addressing mode.
Install went smooth. Although I did notice that fdisk reported the
disk as having NORMAL mode.

After install was done I proceeded with the reboot.

Up to the "Default: F1" prompt all went fine. Thereafter all that
happenned was the appearance of a "-" (or "_") below the D from Default
and that was that.

So, how to proceed. I assume that it is somehow getting the wrong
disk parameters although I would've thought at this point all goes
through the BIOS.

What I'ld do just as lief is booting through diskettes, telling it
which disk to use and be done with it. However that is not as simple
as it ought to be. I manage to boot and access the fixit disk, but not
more than that. The root still points to some diskette and when you
exit it wants to reboot.

During the boot process I did manage to list some disk specifics:

disk1s1a: FFS    40 MB (63 - 81983)
disk1s1b: FFS   132 MB (81983 - 354143)
disk1s1e: swap   20 MB (354143 - 395103)
disk1s1f: FFS  4694 MB (395103 - 10009440)

Finally, when booting under Linux (floppies) that does detect the
correct BIOS parameters.

If anyone has some pointers, please be so kind.

Roelof
