Problem with grub-0.5.96.1, Kernel 2.4 & 1GB physical memory

[Martin Weinberg]

Folks,

We have dual PIII boxes that are using Grub & bootp for a network
boot.  Root is on a ramdisk.

We recently upgraded the Linux kernel 2.2.17 to 2.4.10 and found 
that the kernel can not find the ramdisk on boot up with 1GB of
ram.  No problem with 512GB of ram (I pulled a DIMM).

I tried mem=1024m, mem=512m, mem=1008m (the ramdisk is 16m) but
no luck.  Any idea what I am missing to do diskless boot with Grub,
Linux 2.4.10 and 1GB of ram?  Thanks.
