[PATCH 3/6] vgabios: vbe 15h func returns constructed EDID
by Hiroshi Miura(＠osmf) 01 Sep '12

01 Sep '12

The Bochs VGA ROM now return an information about a recent WIDE monitor. It is constructed from defitions at run time. Returning an EDID with decent timings may be necessary in case we want to use a resolution superior to 1024x768 with Xorg.

[PATCH 2/6] bochsvga: Implement vbe 15h function
by Hiroshi Miura(＠osmf) 01 Sep '12

Posted Wed Mar 7 03:41:07 CET 2012 This patch adds the ability for the Bochs VGA ROM to return information about a generic SVGA monitor. It uses a hardcoded EDID for now, but we can easily immagine contructing an EDID at run time with the help of some support code. Returning an EDID with decent timings may be necessary in case we want to use a resolution superior to 1024x768 with Xorg. Inspired by this patch I digged out from the vgabios mailing list: http://old.nabble.com/VBE-BIOS-support-for-monitor-information-(EDID)-td229… Untested with Xorg.
