Hi Mark,

In order to get Solaris 10 working with Linux, you cannot have any Linux
swap partitions as primary partitions. They have the same ID# as a
Solaris partition so one or both of the OSes flip out. At one point I
was triple-booting between FC4, FreeBSD, and Solaris 10. This was my
partition scheme (if my memory serves me right):

/dev/hda1: Linux root partition
/dev/hda2: FreeBSD (uses its own sub-partitioning scheme)
/dev/hda3: Solaris (see above)
/dev/hda5: (extended partition)
/dev/hda6: Linux Swap
/dev/hda7: Linux home partition

To do this, I booted with a FC4 install disk, then manually partitioned
the disk using fdisk from one of the virtual terminals. Without
installing Linux, I rebooted and put Solaris on (since you don't have an
option to not install its bootloader). Once Solaris was up and running,
I put FreeBSD on, then finally Linux. You can use a chainloader command
for both FreeBSD and Solaris in the grub boot menu.

Let me know if you need more details.

Aloha,
