You've got hardware problems. The address 0x82 is the address of the
first drive on the second controller. In order to boot, the BIOS has to
be able to talk to the boot sector of the drive. 

Here's a test: pull the IDE cable off the Linux drive an put the primary
IDE cable from the windows drive onto the Linux drive. If the drive
tries to boot (i.e you see the lilo screen) the bios is crapped. If it
does nothing, the drive is crapped.

A work around might be to put the Linux drive on the same cable with the
windows drive. Be sure to set up the Linux drive as slave to avoid all
sorts of fun.
