ASL - Marquis C435 Tech Notes

Linux
ASL 2.4.19-2 kernel or higher is recommended for best functionality. Earlier kernel releases do not have the updated IDE driver to support the onboard Ultra ATA/100 controllers.

Nvidia GLX driver version 1.0-4191 or higher is required for AGP 8X and 3D acceleration support. The built-in VGA driver from XFree86 can only support 2D acceleration.

USB
USB 2.0 requires the runtime module ehci-hcd found in ASL 2.4.19-1 kernel or greater. This driver replaces usb-uhci, which is the default USB 1.1 driver. ASL recommends using the USB 2.0 driver for optimal performance. As shown below, USB 2.0 provides superior performance over USB 1.1 interface:

Hdparm
Iomega ZIP 750 with 750MB cartridge = 6.08MB/s (USB 2.0 mode)
Iomega ZIP 750 with 750MB cartridge = 977.57KB/s (USB 1.1 mode)

In addition, external CDRW drives featuring high speed USB 2.0 will only burn successfully using ehci-hcd driver.
