this version will get rid of those double characters.


I found pxelinux get very confused with complicated config files.
This one works just fine for me (both nfs root and local root)


You can also see the kernel config I'm using at (2.4.23)

/dev/sda* is wrong (unless you've hacked your 4801 to contain a SCSI
card) use /dev/hda*

You also shouldn't include the serial line as that will cause double
output.  It's important to make sure /boot/boot.b is the 'text'
version not the menu version.

I threw my lilo.conf at:


To get lilo going, It's easiest to pxe boot the kernel with a local
root fs (not nfsroot), then run lilo as the cf will already be mounted
on /
