[syslinux] Re: SYSLINUX digest, Vol 1 #196 - 4 msgs

[Geddes]

Thanks for the info sylvain. I tried what you suggested and root=/dev/rd/0 
did have an effect however didn't solve the problem. When I set my 
configuration in this manner:

kernel linux.1
append initrd=linux.2 root=/dev/rd/0

I get this result

Loading linux.1....................
Loading linux.2.........................................................
Ready.
Failed to free base memory, sorry...
Uncompressing and Loading Imaging. Please wait...
OK, booting the kernel.
Kernel panic: I have no root and I want to scream

Note before I had the same result except my kernel panic error was:
Kernel Panic: VFS: Unable to mount root fs on 01:01

Another thing that might help in the trouble shooting is here is what my 
logs look like for the tftp server.

Sep 17 13:14:47 bluebruda in.tftpd[18056]: RRQ from 131.202.242.198 
filename pxelinux.cfg/default 
Sep 17 13:14:47 bluebruda in.tftpd[18057]: RRQ from 131.202.242.198 
filename fcs.msg 
Sep 17 13:14:52 bluebruda in.tftpd[18059]: RRQ from 131.202.242.198 
filename linux.1 
Sep 17 13:14:53 bluebruda in.tftpd[18060]: RRQ from 131.202.242.198 
filename linux.2 

To me everything looks fine... except for this model of IBM 6282-73U I 
can't mount the root file system. Where as the exact same setup will work 
on other machines.
