PXE Booting openSUSE, gives ‘invalid or corrupt image’

[rfelsburg]

When I boot using PXE Boot into openSuse, from the menu, I get an error saying 'invalid or corrupt kernel image'. The initrd.img file, and vmlinuz file were both copied from a openSUSE 11.2 system, which is what I'm trying to setup PXE Boot for. PXE Boot works fine, dhcpd, and tftpd both work fine, the box receives an ip, it is directed to the proper file which I know by viewing the log file /var/log/messages, they are at the bottom so you can see them.

initrd.img and vmlinuz were copied from initrd-2.6.31.5-0.1-default and vmlinuz-2.6.31.5-0.1-default respectively

What are you exactly doing?

Insofar I know PXE-boot is used to boot a computer on which no OS is installed.
You boot via the network from another computer which is set-up as a PXE-boot server.
The computer on which you boot must have the BIOS ability to boot as PXE-boot.

So PXE is not for booting a computer on which suse already is installed.

[rfelsburg]

Okay,I know exactly what PXE Boot is used for, right now it's setup to boot for multiple CentOS and multiple Fedora versions.

openSuse being on the laptop currently has nothing to do with me trying to run an openSuse install from my PXE Boot server, I was merely giving information as to where I got the initrd.img and vmlinuz files.

[rfelsburg]

Heres a cleanup of the above data. As well as the inclusion of a tcpdump during the pxeboot process.

When I boot using PXE Boot into openSuse, from the menu, I get an error saying 'invalid or corrupt kernel image'. The initrd.img file, and vmlinuz file were both copied from a openSUSE 11.2 system, which is what I'm trying to setup PXE Boot for.

Sorry chap, I really don't have an idea of what you are doing.
Copying what to where and so on.
But maybe someone else here has.

Anyway, it might help to look at:
