My Optiplex 755 has the latest bios (A11) already, I don't think its a
hardware or bios problem because my testing has shown that on the bare
metal the same kernel boots successfully with the sata in legacy or
ahci mode both the cdrom and hd are detected, but booted under Xen the
hd is not detected in either mode.
On friday I changed the grub.conf to enable serial console as I will
not be at the office until tuesday but unfortunately I am not getting
any grub serial menu so the machine is stuck in a reboot loop for the
next 3 days, next week I plan to put a root filesystem on a usb memory
stick to see if I can boot a OS that way and do more testing while the
hd issue is sorted out.
