Does the BIOS support ATA-133?

If the drive is on a controller card, is it in fact an ATA-133 card, as opposed to an ATA-100 card?

Real-world performance gains from having ATA-133 vs. ATA-100 are virtually non-existent (unless you were using a RAID 0 or RAID 5 array and a very demanding application), since the "133" and "100" MBPS numbers refer to the maximum initial burst speed, not a sustained data transfer rate.

Athlon 1.1 - 512 MB RAM = 98SE & XP Home

Athlon 3000+ 64 - 1024 MB RAM = 98SE (@768 MB RAM) & XP Pro

IBM ThinkPad PIII 900 - 384 MB RAM = 98SE & XP Pro SP2
