Subjectlilo append mem problem in 2.4.20

Compaq proliant 5000 4 way Pentium Pro with 1 GB RAM only uses 12 to 13 MB of
RAM when I use kernel 2.4.20 with ac1 patch even when I do append="mem=1024"
in /etc/lilo.conf

RH 7.2 is the distro and its default kernel (2.4.7-10smp), works flawlessly
with the mem append, it sees and uses all the RAM. But, their latest kernel
2.4.18-18.7.xsmp fails to use the RAM as well; it too only sees 12 to 13 MB...
this is why I tried the kernel.

I used RH's 686-smp kernel config file to build the 2.4.20-ac1 kernel. I
turned High Mem support off as I don't think 1 GB is high mem... is it? Anyone
know how I can use all of the RAM?

Here's the lines from /var/log/messages for each kernel:

2.4.20smp-ac1 = Dec 4 13:44:48 localhost kernel: Memory: 12700k/16384k
available (1396k kernel code, 3168k reserved, 102k data, 240k init, 0k

2.4.18-18.7.xsmp = Memory: 13156k/16384k available (1269k kernel code, 2712k
reserved, 90k data, 220k init, 0k highmem)

2.4.7-10smp = Memory: 1026788k/1048576k available (1396k kernel code, 20376k
reserved, 102k data, 240k init, 131072k highmem)

Thanks a bunch,
