ABIT Introduces Gentus™ Linux:

“With Gentus we have really gone out of our way to make it easy to set up and install.
Specifically we have added direct support for UDMA/ATA/66 drivers so that you can install directly to an ATA/66 drive, with a fixed driver and driver optimizations for UDMA66” explains ABIT’s Smith. “Previously, users had to first install in the ATA/33 mode then later switch over to the ATA/66 channel. With our software enhancements to the Linux kernel that has all been obviated and the process is much more smooth.”
