Kevin O'Connor5c4a8c62008-05-12 23:50:16 -040013Look into ways to reduce stack usage. Alter ISRs so that they do not
14enable irqs. Only call out to other bios functions after minimizing
15stack usage.

Kevin O'Connor7a558e42008-03-11 20:38:33 -040017Audit all sti/cli calls. Audit all call16 calls to make sure flags is
18setup properly with respect to irqs.

Kevin O'Connored128492008-03-11 11:14:59 -040020Audit statements where a 32bit intermediary changes meaning of a 16bit
Kevin O'Connor63dbcfb2008-03-01 22:17:07 -050023Code assumes ebda segment is static - it doesn't read 0x40e.
Kevin O'Connorb8aacb02008-03-01 14:56:07 -050025The __call16 code does a long jump to the interrupt trampolines - this
26is unnecessary.
