Re: Fdisk Question

[Louis Bertrand <louis@bertrandtech.on.ca>]

I just went through that exercise with a 12G disk.

The OS ignores the BIOS limitations once it's booted.
Somebody mentioned on this list recently that the fdisk partitioning is a
way of telling other OSes that the space is reserved. OpenBSD only looks
at the disklabel to figure out where it can play. That seems to be the
case.

I used the DOS pfdisk utility from the distribution CD (get a windows boot
floppy if needed). Edit disklabel in blocks, not cylinders. I didn't want
to take any chances so I calculated the start, stop and sizes with a
spreadsheet, especially since I had made a mess of things by experimenting
earlier with Linux, FreeBSD and NetBSD.
