We've moved to GRUB 2 as a development platform. Please can you check if this bug still applies there, and if it does, reopen it?

Thanks

Boot memtest86+.bin from grub like this
title MemTest86+
kernel /boot/memtest.bin

usually work, but, if we set video mode, for example

setvbe 800x600x32
title MemTest86+
kernel /boot/memtest.bin

Result in black screen.
Memtest seems working, and reboot on ESC key, but we can see nothing on screen.

Maybe we must change video mode to standart textmode before boot something?

#trunk/stage2/stage2.c
/* Attempt to boot an entry. */

boot_entry:

cls (); <- setvideomode(0x03) ???
