[LinuxBIOS] i810 support on its way!
by Corey Osgood 19 May '07

19 May '07

Intel i810/i82801aa/b support should be on its way soon, I hope the folks that were asking about it are still subscribed. i815 will follow soon after. minicom.cap attached, I've still got a few quirks to work out (like finishing the south bridge and a quick fix to ram size setting), but ram init seems to be working. Expect more in a couple days. Asus MEW-VM is the current target board, for anyone curious. BTW, SMSC LPC47B272 is listed as unknown on the wiki, I can confirm that at least the pre-ram code works. Also, if anyone has any info relating to the setting of the buffer strength, neither datasheet is clear on it, just that it depend on if the ram is x8, x16, or x32. I have x8 and x16 ram sticks that I can test how the factory bios sets up, but I think the only x32 stick I have is 512mb, which is more than the i810 supports. -Corey

[LinuxBIOS] [PATCH] fix whitespace for Intel xe7501devkit Config.lb
by Corey Osgood 19 May '07

19 May '07

Just went to look at this for reference, and noticed the whitespace in the device section was a mess. Attached patch fixes that. No actual code changes, just fix the whitespace so it's legible. Signed-off-by: Corey Osgood <corey_osgood(a)verizon.net>

Perhaps it is better to keep this kind of thing mainboard specific. I'll work on moving the code to mainboard.c file.

These should all be ADT7463, rather than ADT7643. Can you fix that? Thanks, Ward. -- Ward Vandewege <ward(a)fsf.org> Free Software Foundation - Senior System Administrator
