If you have to do this, be sure to re-enable your cache when you are finished with installation, as the system runs much slower with the cache disabled. It may be something that Linux can work around. We'll continue to look into the problem. When disabled, the installation floppy was not read correctly, and the system eventually crashed. In addition to your BIOS settings, you may have to change some settings on the actual cards.
Some cards have setup menus, while others rely on jumpers.
The Linux Kernel can not always detect what amount of RAM you have. If this is the case please look at Boot Parameter Arguments, Section 6.1 .
