This forums is for OS project announcements including project openings, new releases, update notices, test requests, and job openings (both paying and volunteer).
Some code is not commented yet and there are some bugs, but I release a preliminary 0.1.1 only to osdev.org for now. It is written in assembly.
You can play a bit with the kernel to find some potential bugs I have not spotted yet. Try also to change the kernel to test functions that are not in use. Remember: it is still in pre-alpha.
Also, you need to run it on a real machine or in an emulator that can emulate USB.
Known problems:
Ext2 code stops at singly indirect blocks.
USB flash drive turns off after some time.
Ok, here it is. Thank you for the suggestion. Also, I overcame a limitation of "display_scroll" and now if the pixel row isn't at a multiple of 16, it scrolls that many rows just to fit the next line. Try it by changing "mov dword [pixel_vert], 0" to any value you want in "kernel.asm".
Now I will start commenting the rest, and fixing remaining bugs and limitations. To help, please report them.
Ehci controller code not commented yet, but I think it is OK to release RC4 with improved ext2 code. Next Monday I expect releasing the final 0.1.1 release (where everything will be commented and code style will be consistent).
Edit: Is there someone that could review my ext2 and ehci code?
Happy testing (I hope this is the last time before final release),
