Two HDDs:

160 GB (Ony Windows XP and Windows 2003 Server) (Windows Boot Loader)

so when i change boot sequence from 160 GB HDD to my 80 GB HDD and boot successfully to solaris

but when i try to boot to Linux I get the following Error Or Warning Message:

Biso Bug : Legacy Free FADT Detected but FADT Size (128) Is Incorrect.
