Hi Vladimir, We encounter an error message "no suitable video mode found" when booting a VM on i386 platform. Though I think this is not a big problem, but the LinuxKit guys(we use grub2 in LinuxKit project) have some concerns about this error message, so I submit a patch[1] try to eliminate this message. Would you please take a look at that patch?
I also dig into the commit logs of the grub2 git tree, and found below commit: commit b1257f653367e8d21b625276f53f086d68fab0b3 Author: Vladimir 'phcoder' Serbinenko <[email protected]> Date: Tue Aug 16 16:11:10 2011 +0200 Don't accept text modes on EFI when booting Linux. * grub-core/loader/i386/linux.c (ACCEPTS_PURE_TEXT): New define.
