Subject: Move POST stack from 0xfffe to 0x7c00.
X-Git-Url: http://wien.tomnetworks.com/gitweb/?p=seabios.git;a=commitdiff_plain;h=bf5ff17db0eb51b65652f95ff760276bbb1db2c4

Move POST stack from 0xfffe to 0x7c00.

The BIOS Boot Specification recommends 0x7c00 - 0xffff for option rom
    temp storage, so don't use that space as a stack.
Also, default CONFIG_VGAHOOKS off as it isn't generally useful.
Finally, update TODO list.
