I use coreboot 4772 with SeaBIOS (the same is on
SeaBIOS stable 1.7.2.1 and new 1.7.3) I noticed bad display screen in VESA mode
after restart WinXP OS (no ACPI). Bad screen is only after WinXP reboot in any
program which use VESA mode e.g. coreboot logo, PLOP menu, PXElinux menu,
Acronis Disk Director tool etc.
If boot PC from PXElinux menu with menu.c32 (text
mode) have no display problem.
If use vesamenu.c32 in pxelinux then have display
problem.
This means that this is
a problem VESA mode only.
Appear
on the screen as if it was divided into
sections the size of one
character text about 4x12 pixels. My image size is 640x480.
This means that screen size is 160x38 or 160x40 text
character:
640 /
160 = 4
480 /
40 =
12
