Only 64 out ot 256 meg memory found

Running an AMD k7-500 w/ an Asus motherboard and 2-128meg pc100 dimms.
/proc/meminfo & top both only report 64 meg of memory. 256 Meg does
show up in bios and when booting win98. I have not tried installing the
6.1 version yet.
Try adding append="mem=256MB" to the linux stanza of your /etc/lilo.conf.
The same happens with RH 6.1 and 2 x 256 MB DIMM on the same board (ASUS K7M):
it only sees 64 of 512 MB. Adding "mem=512M" to the boot options in lilo.conf
solved the problem.
My IBM Thinkpad 385D only see 64M; adding 'append="mem=80"' to /etc/lilo.conf
fixes it. I thought the 2.2 kernel series was not supposed to have the 64M
It relies on a working BIOS to see over 64Mb. This causes the problems. 2.4
tries to use the same
BIOS interface as Windows does on the basis the vendors might actually have
I have a kernel crash at boot with the kernel option set to "mem=256M".
The kernel boot, and recognize 255M of memory with the kernel option "mem=255"
instead of "mem=256".
