OK, I just got a new Maxtor 40GB ATA133 @ 7200RPMs...Whenever I put it in my computer, it tries detecting it as soon as the computer boots, but never finds it...I set the jumper from Cable Select to Master and still the same problem... Is this HD backwards compatible with ATA100 (I think its ATA100, correct me if I'm wrong)? //edit: I'm thinking I need a BIOS upgrade...If anyone finds anything with the following, please let me know: BIOS Date: 07/31/98 BIOS Type: Award Modular BIOS v4.51PG BIOS ID: 07/31/1998-i440BX-W977TF-2A69KQ19C BIOS Eval: P6I440BX/B1 BIOS V1.2SL Jul.31,1998 Chipset: Intel 440BX/ZX rev 3 Superio: Winbond 977TF rev 0 found at port 3F0h
