I'm trying to install NetBSD 1.3 to the second partition of a 2GB disk
in a really old Gateway. Since the BIOS does not support LBA, I had to
install this "ONTRACK drive overlay" thing. Going through the process
to boot from a floppy, and then running pfdisk, I made the following
paritions:
1 7 0 511 WinNT
2 65 512 1021 BSD
The disk geometry is 1022 64 63 LBA, 4092 16 63 real.
I have NT installed on the first partition, an action that I would very
much like not to repeat. When I boot the NetBSD install floppy (through
the overlay thing, but I suspect that doesn't matter), sysinst says that
the "BIOS" geometry is 1024 16 63 (meaning that it is kicking the
overlay thing out of memory?). So I set this to 1022 64 63 and
continue.
The problem is that when sysinst gets around to partitioning the disk,
it claims that there is only one partition (0-4092). I suspect that
this is because when the overlay thing is in memory, the partition table
is at a different location than when it is not in memory (based on my
experience with pfdisk when I forget and boot directly from the floppy).
I'm affraid to edit the partition table with sysinst and overwrite
something that isn't the partition table. I didn't see any mention of
these overlay things in the install doc, so I'm wondering if anybody
knows of a workaround.
