[LinuxBIOS] Add initial support for intel i855gme northbridge
by Jon Dufresne 20 Jan '09

20 Jan '09

Add initial support for i855gme. This is a work in progress and I don't expect it to work on all boards, or even any besides mine. This is based heavily on i855pm. Signed off by Jon Dufresne <jon.dufresne(a)gmail.com>

[LinuxBIOS] A8N5X port
by Robert Millan 21 Nov '08

21 Nov '08

This patch includes config files for the asus/a8n5x port. It is the same as asus/a8n_e with a different pnp layout, so I used #include's whenever possible. System boots and is usable with usb keyboard. works: - serial port - vga (old pci card) - memtest86+ succeeds, but only with Rudolf's patch for unbuffered dimms in K8. Otherwise you get spurious memory corruption. - ide disk - usb doesn't: - ps/2 keyboard - onboard ethernet - vga pci-e card (??) - any other pci card I tried wasn't tested: - sata - game port - onboard audio (not supported by alsa anyway) - ps/2 mouse -- Robert Millan <GPLv2> I know my rights; I want my phone call! <DRM> What use is a phone call, if you are unable to speak? (as seen on /.)

[LinuxBIOS] flashrom support for AMD Geode CS5536
by Lane Brooks 16 May '08

16 May '08

Attached is a patch that enables AMD Geode CS5536 chipset support. I have tested it successfully on a MSM800 board from digital logic. It does, however, have a few issues that I would like some feedback on. In my discussions with Marc Jones, Geode systems write protect the BIOS via RCONFs (cache settings similar to MTRRs). Unlocking requires changing MSR 0x1808 top byte to 0x22. Reading and writing to the msr, however, requires instrucitons rdmsr/wrmsr, which are ring0 privileged instructions so only the kernel can do the read/write. So my patch uses the msr kernel module to access these instructions from user space using the /dev/cpu/0/msr device. My questions are: - I do not think this is portable beyond linux. Is that an issue? - My code assumes the msr kernel module is already loaded. Is there a way to force a kernel module to load from the C code? My code does die gracefully with a message reminding them to load the kernel module if things fail. - It seems like there should be a way to revert the msr back after flashing is completed to put the bios back in write protect mode. Is there a cleanup mechanism available? Something like disable_flash... Thanks, Lane Brooks

[LinuxBIOS] W39V040BPZ or vt8237. Flashing problems.
by Adam Talbot 04 Mar '08

04 Mar '08

Have three motherboards running cn700, VT8237 chips set. All three boards have W39V040BPZ bios chips. I can not program them with flashrom. Flashrom see the chip as W39V040B. Flashrom start on the flash and just sits there. When flashed with the -V option I can see the memory address is not changing. But, big problem is the fact that the chip does get a bit flashed, as, I can no longer boot. So there is something happening. Looking at the data sheet for the W39V040B, all the PZ gives me is the PLCC package and lead free. So, is this a problem with the vt8237 south bridge? Where should I go to start debugging? -Adam

[LinuxBIOS] [RFC] i82801 generic patch
by Corey Osgood 30 Dec '07

30 Dec '07

The attached patch is a unified version of the current ports of the i82801 series currently in LinuxBIOS. Since most of the ports are nearly identical, I've taken for each file and chosen the cleanest or best version of the code, then checked over the datasheets to *some* of the series, including the aa, ba, ca, and db, to make sure that it would work. I've also made some changes here and there, mostly cleanup and clarification. The only things left to look at are the huge difference between this version's lpc init and the i82801er's, finding a better way to select which chip is present on the board, and gpl headers in all files. Anyways, comments, suggestions, even flames are welcome ;) Testing on other chips can be done at this point as well, this is tested and working on one model, the i82801aa. -Corey

[LinuxBIOS] [PATCH] Remove Bitworks IMS
by Corey Osgood 01 Dec '07

01 Dec '07

Well, as there seems to be a lot of cleaning up going on lately, might as well add this to the docket. The attached patch removes the Bitworks IMS, as 1) there's no video support for it, 2) no one objected when this was discussed previously, and 3) no one seems to have one, and they aren't readily available. Any comments are welcome. Signed-off-by: Corey Osgood <corey_osgood(a)verizon.net>
