BIOS set to auto find drives. I went in and manually searched from within BIOS which found drives OK. I have now reflashed BIOS with same version. Boot up time now 2 minutes or so. But still won't boot without windows CD in Drive. Even though I have been in and changed boot drive priority to floppy/HDD/CDROM. it boots a little faster obviously with floppy/CDROM/HDD.
So although P.O.S.T seems to be working and recognises drives, BIOS is seems to see my drive priority changes, it does see/accept HDD when it tries to boot.
Solved at last. Followed Catweazle guide and took machine back to bare bones. The culprit was the last item connected, the DVDRW (LITE-ON DVDRW LH-20A1H). It Didn't like being setup as a slave drive. Had to set it up as secondary master. I've had LITE_ON drives before but not with this problem.
Thanx to dcc for responding an to Catweazle Guide
