Re: DDR problem
by Dave Ashley 17 Jul '03

17 Jul '03

I think this problem is configuration of Rx58 bits 7-5, you have 10/11 bit column address but it is behaving like 9 bit column address. From looking at the code for ddr init it looks like cpu address shifted right by 3 bits is the address going into the chip. So accessing 0x150 is really like accessing 0x02a on the ddr chips. Accessing 0x1000 is chip address 0x200 which overflows 9 bits. I can get this same behaviour with to DDR rams. However when I try to configure ddram control matching award bios settings, it works better but fails later during vga init I think. Passes ramtest also. -Dave >SDRAM verify: >00000000:00001000 >00000004:00001004 >00000008:00001008 >0000000c:0000100c >00000010:00001010 >00000014:00001014 >00000018:00001018 >0000001c:0000101c >00000020:00001020 >00000024:00001024 >00000028:00001028 >0000002c:0000102c >00000030:00001030 >00000034:00001034 >00000038:00001038 >0000003c:0000103c >Too many errors.

ADLO, Framebuffer et al.
by Stefan Reinauer 17 Jul '03

Hi, I noticed that for video initialization I need to keep a copy of the video rom in the system rom for execution. This definitely makes sense for onboard graphics, but for other devices it would be nice to just use the option roms held on expansion cards. (Like Video cards, SCSI controllers, network cards, etc) Is this just a matter of mapping the roms into address space, or is there some higher magic preventing this to happen? Stefan.

Hi, On Wed, 2003-07-16 at 21:21, Marco Hetzel wrote: > Hi! > I'm sorry, but I don't know what to do. I asked in Forums and in this mailing-list, but noone simply answers my questions or gives me a link to a page that answers them. So I try to write you :)! > I've got a Asus A7N8X - Mainboard with NForce2 Chipset. Is it anyhow possible to run LinuxBios on it? You don't have to answer long. But pleas send me any links, that you have to this issue. First, you have to look what kind of northbridge/southbridge you have (lspci), then look for the model of chipset inside the directories (src/northbridge and src/northbridge) if there is the chipset implemented probably you will can run LinuxBios, else you have to port it. You can see info in: http://www.linuxbios.org/developer/portguides/sbc710/index.html Xavi.

Recommendations for ROM/Flash emulator
by Nick Jarmany 16 Jul '03

16 Jul '03

Can anyone give some recommendations on ROM emulator hardware? We want to get stuck into LinuxBIOS on a new board design using the SiS661FX, but would like to ease the process of recovering from broken code. A decent emulator with fast download speed and an auto-reset would seem to be the way to go. Does anyone have suitable hardware that they would thorougly recommend? Nick P.S. Ollie - are you doing any work on the newer SiS chipsets? Is your work confined just to LinuxBIOS or do you have other interests in the Linux field related to SiS hardware, e.g. graphics? ************************************************* Registered Office: Densitron Technologies P.L.C.

Hi, i almost finnished the documentation that i collected about LinuxBios, you can see this in http://www-est-fib.upc.es/~e6058836/projecte.pdf, i'm open to critics, suggestions, etc ..., in this document only i put the information that for me was useful to understand LinuxBios. I think that it can be better if i put some information about PCI (i have no time for this at the moment), for the rest, i think it's enough. Thanks a lot. Xavi.

AMD64 & LinuxBIOS
by mmmooretx＠earthlink.net 15 Jul '03

I am interested in assembling a CAD/CAM & Gaming machine for my home LAN. The chip is due out mid Sept. I have no details on the motherboard yet. I run SuSE 8.2 Pro at home now. Any inputs would be appreciated, rumors too... If there was an Opteron motherboard with an AGP slot I'd go down that path...

building HDAMA the old way and the new way:
by ron minnich 15 Jul '03

15 Jul '03

The jmp for fallback is wrong from what I can see. At 0xffff0 I have this: 0: e9 11 00 00 00 jmp 0x16 in other words, the segment is 0000, not f000. The 32-bit is ok: 0: e9 5b 00 ff ff jmp 0xffff0060 This is happening with both old and new config tools. the _start symbol is a T symbol at 0xffff0004 in linuxbios.map. The correct ldscript.ld files are being loaded. Any suggestions? thanks ron
