[LinuxBIOS] DRAM Intialization...
by sanjay tiwary 06 Mar '07

06 Mar '07

In continuation with my last posting on the mailing list "Nothing Happens after "Jumping to linuxbios"", What are the things that should be taken care of while DRAM Intialiasation, because i am able to read/write the ram. Because after copying the boot code in ram , it tries to Jump here but not able to execute hardwaremain code. Pls do suggest something.

[LinuxBIOS] mcp55 flashrom problem
by Ward Vandewege 06 Mar '07

06 Mar '07

Hi all, Richard and I spent most of this evening chasing a suspected hardware problem that turned out to be not a hardware problem, but a flashrom problem. Basically, I had made a copy of the rom with flashrom earlier today, and Richard soldered a PLCC socket onto our board this evening. After that, the board booted fine, but when reading out the rom image with flashrom again, it came up as slightly different - 115 bytes of difference out of 512K. Eventually, we realized that the image we read out *changed after every boot*. We also diffed the image that is downloadable from Gigabyte of this particular BIOS revision, and it's nothing like what flashrom returns. While they are the same size, the flashrom copy looks like it is uncompressed (and only part of the real BIOS), while the downloadable image has hardly any recognizable strings in it - it's probably compressed somehow. It looks like flashrom is not disabling shadow properly. This is probably related to my patch of earlier today that added a new pci id for this particular board's MCP55 (0x0360). Flashrom only knew about 0x0364 and 0x0367 for the MCP55. I also saw a patch from Ed Swierk a couple of weeks ago, which added a whole bunch of PCI ids for the MCP55 (among which the 0x0360), but was never applied to the tree. Can someone who knows the MCP55 have a look at the enable_flash_mcp55 function in flash_enable.c and figure out what's wrong? Yinghai, can you tell us which board(s) you've tested the enable_flash_mcp55 function on? Thanks, Richard and Ward. -- Ward Vandewege <ward(a)fsf.org> Free Software Foundation - Senior System Administrator

[LinuxBIOS] MenuetOS and LinuxBIOS?
by Uwe Hermann 05 Mar '07

05 Mar '07

Hi, someone added MenuetOS (http://www.menuetos.net/) to the list of LinuxBIOS payloads in the wiki. MenuetOS seems to be a small (1.44 MB), graphical operating system written completely in assembler. And it's GPL'd. Has anybody ever tried using it with LinuxBIOS? FWIW, it runs just fine in QEMU: wget http://mesh.dl.sourceforge.net/sourceforge/menuet/M32-084.ZIP unzip M32-084.ZIP qemu -fda M32-084.IMG -std-vga I'm not so sure whether it will run using LinuxBIOS, though. From looking at the code it seems to do BIOS (interrupt) calls, if I'm not mistaken. Examples: SHUTDOWN.INC: mov ax,0x0000 ; reset drive mov dx,0x0000 int 0x13 BOOTCODE.INC: mov ah,0x87 int 0x15 Does this mean MenuetOS will not run with LinuxBIOS? Thanks, Uwe. -- http://www.hermann-uwe.de | http://www.holsham-traders.de http://www.crazy-hacks.org | http://www.unmaintained-free-software.org

[LinuxBIOS] Cheap self-built BIOS saviour for 8M/16M parts?
by Carl-Daniel Hailfinger 04 Mar '07

04 Mar '07

Hi, after combing through the SST data sheets for the * SST49LF008A * SST49LF080A * SST49LF016C * SST49LF160C parts, I am fairly sure I found a procedure to have multiple flash parts attached at the same time which should just work. Simply use two chips of the same model, connect all of their pins except ID[0], wire ID[0] of each of the chips to one side of an intermediate switch which is connected to Vcc and GND on the other side. The intermediate switch makes sure exactly one chip has Vcc at ID[0] and the other one has GND at ID[0]. The switch with GND on ID[0] is the one selected. However, you need to drive the RST# pin of both chips to GND for 1µs whenever you want them to change roles during system operation. So you'll need: * 2 identical flash chips * intermediate switch (can be hardware) * a way to drive RST# to GND without shorting the board * serious soldering skills to solder two chips to each other Sounds nice? Surely there's a catch. It can't be that easy, right? Tell me! Regards, Carl-Daniel -- http://www.hailfinger.org/
