Lancelot 1870 Tech Notes

BIOS setting

To maintain low noise operation, always set Fan Speed Control Modes to 3-pin/Server in the BIOS Hardware Monitor section. All chassis and processor fans are monitored in real time under Linux using the included utility (superodoctor).

If the system has 4GB of memory or greater, Discrete MTRR Allocation must be enabled in the BIOS Memory Cache section. Otherwise, system performance will be reduced.

Red Hat Enterprise Linux 3/4 (32-bit)

To reinstall the operating system, always use the ASL RHEL device driver CD (only included on systems purchased with RHEL) when prompted. Otherwise, system stability will be compromised due to the buggy and obsolete drivers provided in the Red Hat kernels.
