#mkdir tmp
#mount -o loop initrd.img tmp
mount: you must specify the filesystem type ## this is the output

so what can i do??

try:

pico initrd.img

or

emacs initrd.img

Hi, I'm a total n00b too. I have file called redhat9.img that is supposed to contain drivers for my gigabit ethernet card. What the heck do I do with this file? I tried viewing it using emacs and pico but I just get a ton of junk on the screen. I also used the "file"command on it and found out that it's of file type EXT2, Linux rev 1.0

HELP
