[LinuxBIOS] [PATCH] Some more 440BX progress
by Uwe Hermann 03 May '07

03 May '07

Hi, here's a first patch for the 440BX code and the Tyan S1846 and the 82371EB southbridge which gets my Tyan S1846 a lot further in the boot process. However, it cannot boot a payload, yet. It seems the major problem was that I did ram_check() on the whole range from 0 - 64 MB (in my case; I use a 64 MB DIMM for testing). This cannot work of course, as the range from 640 KB - 1 MB is _not_ RAM but rather reserved for all kinds of other stuff (thanks Stefan for pointing this out!). Leaving out that range, but checking the rest of RAM, I get a "DRAM range verified", so it seems RAM init _does_ work after all. (it's hardcoded to my board and setup of course, but that'll be fixed) I've tried setting up the PCI devices correctly in Config.lb, but I'm absolutely not sure that I got it all right. Can somebody please check this and let me know of any stupid errors I made? Here's the lspci output from the Tyan S1846: 00:00.0 0600: 8086:7190 (rev 03) 00:01.0 0604: 8086:7191 (rev 03) 00:07.0 0601: 8086:7110 (rev 02) 00:07.1 0101: 8086:7111 (rev 01) 00:07.2 0c03: 8086:7112 (rev 01) 00:07.3 0680: 8086:7113 (rev 02) 00:10.0 0300: 5333:5631 (rev 06) 00:11.0 0200: 10ec:8029 00:00.0 Host bridge: Intel Corporation 440BX/ZX/DX - 82443BX/ZX/DX Host bridge (rev 03) 00:01.0 PCI bridge: Intel Corporation 440BX/ZX/DX - 82443BX/ZX/DX AGP bridge (rev 03) 00:07.0 ISA bridge: Intel Corporation 82371AB/EB/MB PIIX4 ISA (rev 02) 00:07.1 IDE interface: Intel Corporation 82371AB/EB/MB PIIX4 IDE (rev 01) 00:07.2 USB Controller: Intel Corporation 82371AB/EB/MB PIIX4 USB (rev 01) 00:07.3 Bridge: Intel Corporation 82371AB/EB/MB PIIX4 ACPI (rev 02) 00:10.0 VGA compatible controller: S3 Inc. 86c325 [ViRGE] (rev 06) 00:11.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

Also, a full boot log is attached. The PCI init _seems_ to work, at least partially. The current end of the story is that elfboot cannot find the payload, not sure why. Wrong PCI init? Wrong RAM init? Wrong payload location? Thanks, Uwe. -- http://www.hermann-uwe.de | http://www.holsham-traders.de http://www.crazy-hacks.org | http://www.unmaintained-free-software.org

Re: [LinuxBIOS] Iwill DK8-HTX now runs under LinuxBIOS r2587 (Thanks)
by Ning (Michael) Qu 03 May '07

03 May '07

Hi, Alexei, Thanks for your posts on DK8-HTX. I am just starting working on this mainboard these two days. From what you said in your email, you modify several things I think, and most of them must be modified by lxbios, I try to summarize your work: 1 serial console baud_rate -> 115200 2 max_mem_clock -> 400MHz 3 boot_first ("HDD"), boot_second and boot_third ("Fallback_HDD"). I am not sure how to achieve the third one. Is it also in cmos? And another question is that I don't know how to dd a 36K Video ROM as you said. Do you just enlarge the size of dd? such as this? dd if=/dev/mem of=vgabios.bin skip=1536 count=72 Is that all the things you make LinuxBIOS run on DK8-HTX? Thanks for your help!

Forgot to mention that to see the serial console output I also changed the baud_rate CMOS value to "115200"--since just this value was defined in the LinuxBios Config-s and I had set my serial console client (kermit) to wait connection just on this rate.

[LinuxBIOS] Gigabyte M575SLI
by Kevin Adler 03 May '07

03 May '07

Hi, I've been watching this mailing list for a long time mostly to see the progress on the Gigabyte M575SLI and things seem to be looking very nice. I have 2 questions: how easy is it to build the LinuxBIOS and flash it without bricking it? (I've been looking at the sideproject here about using the extra bios socket, but my soldering skills are not very good and I don't have much in the way of decent soldering tools) and also, how easy is it to set what would be normal BIOS settings like voltage, cpu multipliers, etc... (For say overclocking a system) I've heard about a Google SoC project to get some sort of CMOS setup like interface after it is booted, but it seems you have to hard code these values in to the option file before you build the BIOS. Am I correct? And if so, what are all the options you can set? Many thanks Kevin

[LinuxBIOS] Nifty device for SPI chips
by Richard Smith 02 May '07

02 May '07

I just got back from an extended stay in Asia and while I was there was introduced to a nifty little device for SPI flash chips. When the mfgs all switch to SPI it may actually be much easier to deal with non-socket flashes. http://www.dediprog.com/product.php?UID=12 $275 US gets you a programmer + the hardware to hook it up to your board. The way it works is by asserting the HOLD pin on the SPI flash which almost all SPI flash parts have. So the flash thats soldered on board is suspended and you boot from the one in the adapter. The only requirement is to have the HOLD pin pulled up via a resistor rather than tied directly to the SPI part's Vcc. Even if it is tied directly to Vcc working around it would only involve cutting a single trace or lifting the HOLD pin. -- Richard A. Smith smithbone(a)gmail.com

[LinuxBIOS] Booting Windows XP / Vista - Google Summer of Code
by Augusto Pedroza 01 May '07

01 May '07

Hi there, I am very excited for having been selected for GSoC with such a challenging project. My project consists of booting windows Xp /Vista on LinuxBIOS. Right now, I have the following responsibilities: 1. Evaluating which of the following projects will best fit our needs - using a dedicated LinuxBIOS loader (ie. adapting ReactOS<http://www.reactos.org/>FREELDR) - booting Windows on top of Linux using kexec<http://www.xmission.com/%7Eebiederm/files/kexec/README> /kboot <http://kboot.sourceforge.net/> - fixing ADLO <http://linuxbios.org/ADLO> so that it boots Vista/XP and removing the mainboard dependencies in it's code. 2. I have been figuring out what are the main differences in between Windows XP and Vista booting process. I already got some papers by Ron Minnich, Adam Sulmicki ( http://www.missl.cs.umd.edu/winint/index2.html) and Boot Configuration Data in Windows Vista by Microsoft (* http://www.microsoft.com/whdc/system/platform/firmware/bcd.mspx* ). I would appreciate any suggestions, tools you guys think that would be useful. Thanks a lot and hope to have a great summer, -- Augusto Pedroza

[LinuxBIOS] ASUS P5GC-MX
by Luis Correia 30 Apr '07

30 Apr '07

Hi! although it could be hard to port Linuxbios onto this ASUS mainboard (that uses intel 945 chipset), it has a SPI flash in a convenient PDIP8 socket. The BIOS chip is a 4Mb flash part, Winbond 25X40VAIZ http://www.winbond.com/hq/enu/ProductAndSales/ProductLines/FlashMemory/Seri… Just to let you know the goodies that are around these days. p.s. i'm not going to do any linuxbios related testing Luis Correia

I couldn't get it to compile on the S2882. The payload still has some problems, though, as it only allows me to boot to a grub prompt. I don't get it show the grub menu, or boot the default settings,, but I do get a display, so I'm making progress.
