Additional Notes
Promise ULTRA100 Controller driver for ALL Windows versions (9x ... XP).
Found on the Asus Taiwan ftp site.
This is NOT the latest available driver.
Under every Windows I had big troubles (scattering audio and mouse pointer) using later versions, so I decided to upload this one before it disappears.
If you have harddisks which don't require 48-bit LBA - that means smaller than ~130 GB - I highly recommend you to use THIS driver, not the later ones!!!
This time older means better.
