  * Implement file I/O functions (open, read, close) based on gPXE's posix_io support [[ http://git.etherboot.org/?p=people/dverkamp/gpxe.git;a=commitdiff;h=dcf8448c1e922892ee8dc4cf7a238eaebca1a5df | dcf8448c1e922892ee8dc4cf7a238eaebca1a5df ]]

  * Finally debugged why my VGA test case (a 256-byte demo, [[ http://pouet.net/prod.php?which=3397 | tube by 3SC ]]) wasn't working - it was assuming that registers were 0, and I hadn't been clearing them; after taking care of that, it works fine in bochs, qemu, and real hardware: [[ http://git.etherboot.org/?p=people/dverkamp/gpxe.git;a=commitdiff;h=169e9975ba0aea887bf5515f9bbe32466bf3b5e0 | 169e9975ba0aea887bf5515f9bbe32466bf3b5e0 ]]

  * Fixed a bunch of small things in com32_call.c, after which basic file I/O (filetest.c32) works [[ http://git.etherboot.org/?p=people/dverkamp/gpxe.git;a=commitdiff;h=d645d491cf48d7ef48566057b9b8ad6c5418b5d9 | d645d491cf48d7ef48566057b9b8ad6c5418b5d9 ]]

  * Implement more INT 22h functions (AX = 0005h, AX = 0007h, AX = 0013h, AX = 0015h) [[ http://git.etherboot.org/?p=people/dverkamp/gpxe.git;a=commitdiff;h=068eb73795d962cc70336a8159e6e91ecbd5cb68 | 068eb73795d962cc70336a8159e6e91ecbd5cb68 ]]

  * Implement "Resolve hostname" function; resolv.c32 now works [[ http://git.etherboot.org/?p=people/dverkamp/gpxe.git;a=commitdiff;h=01fa277122c8ee33e26a35b7ef890e57b8b485e3 | 01fa277122c8ee33e26a35b7ef890e57b8b485e3 ]]

  * Map Enter key to 0x0D instead of 0x0A; now fancyhello.c32 works [[ http://git.etherboot.org/?p=people/dverkamp/gpxe.git;a=commitdiff;h=d5f9318b8570cf3c489e4d3f8dfe1955cb837024 | d5f9318b8570cf3c489e4d3f8dfe1955cb837024 ]]

  * Rebased comboot work on top of current upstream gPXE tree and pushed to [[ http://git.etherboot.org/?p=people/dverkamp/gpxe.git;a=shortlog;h=comboot-merge | comboot-merge branch ]]
