|The bios is probably not able to detect a 40 gig drive. Many of the older P-II, P-III had a bios limitation that left them unable to detect a drive larger than about 8 gig. There's a few things you can try:|
1) Got into cmos/bios setup and manually configure the drive with a cylinders/heads/sectors setting of 16383/16/63. That's the maximum the bios will see and is about 8 gig. Those figures are also written to the firmware of the larger IDE drives and sometimes will allow the entire capacity to be seen.
2) A bios update sometimes helps but I couldn't locate any downloads for that model.
3) Connect the drive to an add-on ATA card. They have their own bios and can see larger drives.
4) A bios/drive overlay--software that's installed on the drive that allows the usage of the entire capacity even though the bios can't see it. When using that you need to jumper the 'cylinder limiting jumper' on the drive.
