 Without tables in high memory, seabios won't run on your chipset properly.
 it overwrites your tables in the F segment, as seabios itself lives there.

 Also, once there is support for high_tables_base everywhere, the code in
 src/arch/i386/boot/tables.c can be cleaned up and simplified considerably.

Comment:

 All chipsets have support code for high tables now, but they're not all
 tested (and working?) yet.

Comment(by bam <mybigspam@…>):

 If I have CONFIG_HAVE_HIGH_TABLES = 1 (or CONFIG_WRITE_HIGH_TABLES=1),
 etherboot payload can't work:
