Graphics Corruption

[brownjl]

Hello,

I am using ipxe to install windows/linux in undergrad student labs. When installing through ipxe (undionly.kpxe) via netboot this all works as expected. A console menu is served with image background and a number of installation options with a default set for unattended installation.

However, when i initiate the installation through grup (ipxe.lkrn) the installation work fine but the screen is completely corrupt.

I've tried both using ipxe.lkrn to netboot which will load in the undionly image of my tftpserver and also directly with the script local skipping the network boot. I see the same results on both.

The screen corruption happens at the point the menu is loaded and remains until the os install does its first reboot.

Any suggestion or help would be appreciated!

Thanks

James
