| Clean up timer code. Don't use PORT_DIAG as delay mechanism. |
| |
| Disable a20 on jump to 16bit mode. |
| |
| Do a pci scan for ide controllers - don't just assume ISA ports are |
| available. |
| |
| The keyboard driver should detect ctrl+alt+del and reboot the |
| machine. |
| |
| Fix keyboard LEDs. |
| |
| Review changes committed to coreboot, virtualbox, qemu, kvm, and bochs |
| cvs tip. |
| * bochs cvs (1.209) -- all changes synched |
| * coreboot (r3348): 1.163 -- no noteworthy enhancements |
| * qemu (r4675): 1.207 -- supports >4Gig memory |
| * kvm (45a442c): 1.182 -- >4gig, e820 vmx pages, enable cache?, |
| wrmsr in smp_start and rombios32, acpi insrcovr table |
| * virtualbox (r9404): 1.176 -- f11/f12 kbd, lots of mouse changes, |
| logo, set text mode?, int 1589, floppy data rate?, |
| dummy_isr_function, int19 calls post |
| |
| Look into ways to reduce stack usage. Alter ISRs so that they do not |
| enable irqs. Only call out to other bios functions after minimizing |
| stack usage. |
| |
| Audit all sti/cli calls. Audit all call16 calls to make sure flags is |
| setup properly with respect to irqs. |
| |
| Audit statements where a 32bit intermediary changes meaning of a 16bit |
| comparison. |
| |
| Code assumes ebda segment is static - it doesn't read 0x40e. |
| |
| The __call16 code does a long jump to the interrupt trampolines - this |
| is unnecessary. |
| |
| Cleanup setting of ES on GET/SET_BDA |
| |
| Audit code for 16bit protected mode accesses. |
| |
| Support 1ab1 from 16bit protected mode. |
| |
| Verify option roms wont stomp on seabios stack and bss. |
| |
| Possibly implement 32bit pcibios support. |
| |
| Allow one to select adding 32 bit code to 0xf000 or in a separate |
| location. |
| |
| See if it is possible to handle interrupts while in 32bit mode. |
| |
| Look at integrating the lgpl vgabios into tree. |
| |
| Look at usb booting specs. Look at possibly supporting usb |
| keyboard/mice. |
| |
| Add a graphical boot splash screen? |
