The kernel detects only the first 64MB of my computer, instead of the full 128MB. My configuration: CPU: AMD-K7, stepping 2, 500 MHz MoBo: Asus K7M Memory: single 128MB SDRAM DIMM, 100MHz Workaround: Add append="mem=128M" to parameters in /etc/lilo.conf
If you don't want to add an append line to lilo, you can either turn of ACPI in the BIOS or use a 2.4 kernel, which doesn't have this limitation.
