sorry about the multiple reports, bugzilla was bugging out on me (sent a report
to bugzilla)

Looks like the body of the report still didn''t make it, let me try it here:

When trying to do a remote linux installation on a machine with 1GB of RAM
using the PXE setup that ships with RH 6.2 I get the following message:

...
Warning only 960 MB will be used
initrd extends beyond end of memory (0xffef0000 > 0xfc000000)
disabling initrd
...

not surprisingly the initrd is not mounted and the installation cannot
proceed.

the following patch to pxe-linux/nbp.linux/download.c seems to fix this for
me but I don''t know enough about initrd and PXE to be sure that this is
correct:

On a normal LILO boot (after the installation is complete) I don''t get the
above message, instead I get the following and initrd seems to work OK:
...
63MB BIGMEM available.
