Description phil 2000-02-17 14:19:32 UTC

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.

Comment 1 Matthew Miller 2000-02-19 02:55:59 UTC

Try adding append="mem=256MB" to the linux stanza of your /etc/lilo.conf.

Comment 2 Jos Vos 2000-05-17 19:16:59 UTC

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.

Comment 3 scot 2000-06-09 20:40:43 UTC

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
limit anymore?

Comment 4 Alan Cox 2000-08-08 19:43:04 UTC

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
tested it

Comment 5 Julien Liebert 2000-11-23 02:36:50 UTC

I have a kernel crash at boot with the kernel option set to "mem=256M".

Comment 6 Julien Liebert 2000-11-23 13:22:28 UTC

The kernel boot, and recognize 255M of memory with the kernel option "mem=255" 
instead of "mem=256".
