Details:
My goal is to PXE boot a Dell Latitude 10 RT2 Tablet PC to a grub boot manager
menu.
Building and pxe-booting a grub-image succeeded. USB Keyboard's are not
working however.
The BIOS does not support USB Legacy mode.
I've built the latest Grub2 from source on a Debian 6.0.5 32bit host.
I've built the image using the following command:
./grub-mkimage -c grub.cfg -o grub.efi -O i386-efi boot linux part_gpt fat
ext2 normal configfile lspci ls reboot datetime loadenv search lvm help chain
usb_keyboard uhci ohci
My grub.cfg contains:
insmod uhci
insmod ehci
My /etc/default/grub contains:
GRUB_TIMEOUT=10
GRUB_TERMINAL_INPUT=usb_keyboard
I get no errors or warnings, the grub shell loads fine, only the keyboard is
not working.
