[LinuxBIOS] ACPI DSDT tables for mainboards
by Phani Babu Giddi 30 Dec '07

30 Dec '07

Hello All, It appears that the DSDT tables and the related ASL files are present for few boareds in Linux BIOS. If so how are other boards expected to provide the required DSDT table. Does it has to be taken care either by the kernel or intiramfs ? Is Linux BIOS ACPI 3.0 compatible ? The reason I am looking at this is for supporting PCIe hotplug which looks for _OSC method. This has been specified in ACPI 3.0 spec. Regards, Phani

[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

Dear LinuxBIOS readers! This is the automated build check service of LinuxBIOS. The developer "hailfinger" checked in revision 3027 to the LinuxBIOS source repository and caused the following changes: Change Log: All SPI chips mentioned in flashchips.c had their sector size listed as page size. Fix that. Page size is uniform 256 bytes for SPI. A sector/block size field in struct flashchip would be nice, though. Signed-off-by: Carl-Daniel Hailfinger <c-d.hailfinger.devel.2006(a)gmx.net> Acked-by: Corey Osgood <corey.osgood(a)gmail.com> Build Log: Compilation of amd:serengeti_cheetah_fam10 is still broken See the error log at http://qa.linuxbios.org/log_buildbrd.php?revision=3027&device=serengeti_che… If something broke during this checkin please be a pain in hailfinger's neck until the issue is fixed.

[LinuxBIOS] we are Unable to flash in SST49LF004A/B chip
by malatesh 29 Dec '07

29 Dec '07

Hello.... Advance happy New year...... ASRock K8Upgrade-VM800 motherboard is detecting SST49LF004A/B chip,but we are unable to write(flash). what is the procedure for writting programe on SST49LF004A/B chip. we got a information like, remove the SST chip from its socket, strip the two ends of a small gauge wire, insert one end at pin 7(WP#)and the other at pin 32(VCC). Replace the chip, wedging the wires inplace is it necessory to flash the program in SST chip? Please guide us........ Thanks, Malatesh.

[LinuxBIOS] [PATCH] flashrom: fix page size definitions for new SPI chips
