Hi there!
I like to install FreeBSD 2.2.7 (2.2.8) and 3.0 on the same disc.
Because the FreeBSD boot loader looks for the first compatibility slice, it's
only possible to boot from the first installed release (first slice).
I have tried to change the fdisk information for the first slice
(2.2.7) temporarly from BSD to FAT, then it was possible to boot from the 3.0
release. This is not a very useable workaround because after this, I've to
restore the complete disklabel for the first slice to boot from it.
Any other ideas?
fdisk output:
The data for partition 1 is:
sysid 165,(FreeBSD/NetBSD/386BSD)
start 63, size 2088387 (1019 Meg), flag 80 (active)
beg: cyl 0/ sector 1/ head 1;
end: cyl 129/ sector 63/ head 254
The data for partition 2 is:
sysid 165,(FreeBSD/NetBSD/386BSD)
start 2088450, size 2088450 (1019 Meg), flag 0
beg: cyl 130/ sector 1/ head 0;
end: cyl 259/ sector 63/ head 254
disklabel output for partition 1 and 2 are identical:
a: 65536 0 4.2BSD 0 0 0 # (Cyl. 0 - 4*)
b: 524288 65536 swap # (Cyl. 4*- 36*)
c: 2088387 0 unused 0 0 # (Cyl. 0 - 129*)
e: 65536 589824 4.2BSD 0 0 0 # (Cyl. 36*- 40*)
f: 1433027 655360 4.2BSD 0 0 0 # (Cyl. 40*- 129*)

Mike
