files to be placed in target?
by Devi Priya 18 Jul '03

18 Jul '03

Hello, I compiled the linuxbios for mainboard nano (sc1200). I want my bios program in my Flash ROM (4MB). My kernel image will be in hard disk. These are my generated files. linuxbios_payload.nrv2b nrv2b linuxbios.rom linuxbios.strip payload.block linux.bin.gz linuxbios linuxbios.a romimage linuxbios_c linuxbios_payload linuxbios_payload.bin Out of these files which files are to be placed in my Flash ROM and hard disk in my target? I assume linuxbios.rom is placed in Flash Rom, linux.bin.gz placed in hard disk. Is it correct? But I have no clear cut idea with what other files satnds for? Plzz even if I question looks too preliminary help me. _________________________________________________________________ Are you Unmarried? http://www.bharatmatrimony.com/cgi-bin/bmclicks1.cgi?4d Register in India's No 1 Matrimony

How does the VGA Bios code impact using graphics once the system has booted linux? What I'm asking is, if you don't do the extra VGA bios steps, can you still attempt to use X or framebuffer code from linux, or is the VGA bios required to set things up appropriately? Sorry if this is blatantly obvious to everyone, I'm really only just getting started on this stuff.

This is based on Sone Takeshi's work. Thanks to Andrew Ip for committing the update to CVS.

Re: DDR problem
by Dave Ashley 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

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.

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.

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.
