XEN not booting

Mother baord ASUS M2N8-VMX
AMD althon 64 processor
openSUSE
2 GB memory
1 SATA 80gb hard drive
1 floppy drive
1 DVD
and USB

I loaded open SUSE 64 bit and then installed the virtualization tools etc that come with the DVD. On rebooting the first time the system crashed as there was a problem relating to the APIC
MP-BIOS bug: 8254 timer not connected to IO_APCI. I edited the grub file and added “noapci” and that fixed that.

well it allowed tihe system to start booting.

Then I got a ata03 errors and it went into an endless loop. it eventually crashed with a black screen.

On rebooting I notices an error message saying
“failed to obtain physical IRQ15” the same for IRQ14

I have not been able to find what any of this means let alone fix it.

the loop goes

ata3:01 configured for PI00
ata3:EH complete
ata3:01 Exception mask 0x0 SAct 0x0 SErr 0x0 acting 0x6 frozen
ata3:01 cmd… PI036in
cdB
res Emask 0x4 (timeout)
at3:01 Status {DRDY}
ata3 soft resetting link

Can ansy one assist please.
