Kevin O'Connor5c4a8c62008-05-12 23:50:16 -0400[diff] [blame]29Look into ways to reduce stack usage. Alter ISRs so that they do not
30enable irqs. Only call out to other bios functions after minimizing
31stack usage.

Kevin O'Connorb8aacb02008-03-01 14:56:07 -0500[diff] [blame]41The __call16 code does a long jump to the interrupt trampolines - this
42is unnecessary.
