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

Why don't you fix your BIOS rather than GRUB? It is quite
easy for BIOS to ignore int 0x10.

There were suspicions that the bootloader's int 0x10 BIOS video output can prevent the system from booting. The following patch disables any video output which is not controlled by menu.lst.

In order to completely disable video output, one should specify a serial port in the GRUB's menu.lst as a default terminal.

There are 2 drawbacks not solved by this patch:

a) The video BIOS int 0x10 is still required after applying this patch. A better patch should intercept any int 0x10 and emulate sane default responses.

b) The Linux kernel will display the "Uncompressing image..." message through the video BIOS call.
