[rhn-users] grub.conf and ping(live-os) multi-boot

[earl]

i've been trying to "... put the PING ISO into my harddisk and boot from 
it..." as discussed at 
"http://ping.windowsdream.com/ping/doc-2.01/annex.html". i've tried to 
modify /boot/grub/grub.conf (in red hat enterprise linux 5) to be 
similar to the lilo.conf on the website mentioned (grub.conf pasted at 
bottom of email. Red hat still loads fine, however, ping boots until it 
gets to the RAMDISK and VFS lines, here is the error my screen displays 
just before freezing up.

RAMDISK: Compressed image found at block 0
RAMDISK: incomplete write (-28 !=32768) 4194304
VFS: Cannot open root device "<NULL>" or unknown-block(3,2)
Please append a correct "root=" boot option; here are the available 
partitions
0800 97685784 sda driver: sd
 0801 27985784 sda1
 0802         1 sda2
 0805  24994557 sda5
 0806   4466038 sda6
 0807  14673346 sda7
 0808  25559383 sda8
0b00   1048575 sr0 driver: sr
Kernel panic - not syncing: VFS: Unable to mount root fs on 
unknown-block(3,2)

please let me know what I can do to make both partitions boot. thanks in 
advance, earl
