Subject: RE: [Etherboot-users] 1G memory limit and Etherboot
hi, Eric,
I tried a few days ago, using etherboot 5.0.2, mknbi 1.2.6 with different
--rdbase options, but all failed. The kernel is 2.4.13, the initrd is around
64M.
The netbooted client is a 1.5G memory HP Vectra 420. It can successfully
netbooted with 512M memory. But can not boot when memory is added to 1024M
and 1.5G.
The error prompt is something like:
Kernel panic: VFS: Unable to mount root fs on 01:00
I'm using Official kernel 2.4.13, the base system is RedHat 7.1 on HP
vectra 420.
The commands I used to create the tagged images is:
/usr/bin/mknbi-linux --output=./kernel.test.0540 --ip=dhcp
--rdbase=0x5b000000 --rootdir=/dev/ram0 --append="idebus=66 ide0=ata66
ide1=ata66 ro" bzImage initrd
I also tried options, --rdbase=top/asis/0x00300000, all can failed with the
same above problem.
At last I use local hard disk boot, with the same kernel (4G high memory
option enabled), it can boot successfully, then I tried to see the memory
mapping, and get the following information:

Please suggest which method, I can try to netboot the machine. Thanks a
lot.

It depends on what you are doing. With mnknbi --rdbase.
With other bootloaders it varies. The easy solution is to get
a newer kernel.
