I've got OS/2 Warp 3.0 and Linux 1.1.59 on an Asus SP3G revision 1.8 with
Award BIOS 4.50G and an AMD 486DX2/66 CPU.  I can reboot OS/2 to OS/2,
Linux to Linux, or Linux to OS/2; but I get a message about SCSI devices
not synching if I try to reboot (using <Ctrl-Alt-Del>) OS/2 to Linux.  (I
use SCSI hard drives exclusively, FWIW, on the built-in NCR 53c810
controller.)  I'm using OS/2's Boot Manager, with Linux's LILO as a
secondary loader for Linux only.
