I've built a grub ia32 EFI image that works over a serial console with:
./grub-mkimage -p / -d ./grub-core/ -O i386-efi -o bootia32.efi \
boot linux fat serial part_msdos normal
However, when I try it from a video console, I get:
error: no suitable mode found.
Booting however
I've tried adding an assortment of modules to the image:
./grub-mkimage -p / -d ./grub-core/ -O i386-efi -o bootia32.efi \
boot linux fat serial part_msdos normal \
video video_cirrus video_fb videoinfo videotest \
efi_uga echo help lspci
This has the same end result.
>From the GRUB shell I've tried the following:
grub> videoinfo
List of supported video modes:
Legend: P=Packed pixel, D=Direct color, mask/pos=R/G/B/reserved
Adapter 'Cirrus CLGD 5446 PCI Video Driver':
No info available
grub> videotest
error: no suitable mode found.
The grub.cfg I'm booting looks like the following:
serial --unit=0 --speed=115200 --word=8 --parity=no --stop=1
default=boot
timeout=10
menuentry 'boot'{
linux /vmlinuz LABEL=boot root=/dev/ram0
initrd /initrd
}
Can anyone help me understand what I need to do to get basic Linux
console messages to appear on the video console?
Thanks,
