ASL - Marquis K130 Tech Notes

For the latest announcement on ASL kernel and driver releases and discussion on technical issues, please join our Support Forum.

Linux
ASL 2.4.18-6 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.

The kernel parameters mem=nopentium must be enabled in the boot loader. If LILO is used, add the entry to /etc/lilo.conf. If GRUB is used, add the entry to /etc/grub.conf.

USB
USB 2.0 requires the runtime module ehci-hcd found in ASL 2.4.19-1 kernel or greater. This driver replaces usb-ohci, 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.
