[LinuxBIOS] Various Config.lb fixes.
by Jonathan McDowell 13 Aug '05

13 Aug '05

Hi. The attached patch fixes up the Config.lb files for the 4 targets that buildtarget can't currently parse. These are Iwill-dk8s2, technologic-ts5300, totalimpact-briq & newisys-khepri. None of them then compile afterwards for me, but this at least gets them one step closer. Is anyone working on these platforms who has a better fixup for it? Also, Ollie, any word on the udelay stuff? Can you even give me your quick hack to get things compiling so I can see if it's hiding any other … [View More]

[LinuxBIOS] flash_rom output from a sis chipset
by Jeff Carr 12 Aug '05

12 Aug '05

I tried the linux bios flash_rom utility today on a sis based board. I tried to read out the bios as a file. It failed. (output below) flash_rom says: "Trying MD-2802 (M-Systems DiskOnChip Millennium Module), 8 KB". Interestingly, the second google hit of "M-Systems DiskOnChip Millennium 2802" was the linuxbios wiki :) I thought I'd post the output for informative purposes. I'd dig more if anyone was interested. Is the BIOS chip on this machine really only 8KB in size? I find that really … [View More]hard to believe.

I might not think to look in the Porting Guide for VGA Support. I suggest it be another topic off the main page. And maybe the Porting Guide Page should include Ron's latest article - "Porting LinuxBIOS to the AMD SC520"?

Thank you very much. The new page is very helpful. Let me ask a few questions. 1. Does the new page describe onboard and addon card? I expect the MB Config.lb would change for an addon card? I assume the Config file would describe the PCI slots and steps 2 & 3 would be the same for an addon card. 2. testbios is a third choice, which is useful if the VGA image won't fit in the ROM device. Should you move the testbios FAQ info to the VGA support page? 3. Will there be a link … [View More]

[LinuxBIOS] BIOS Savior RD1-PMC4 on VIA EPIA-SP
by Doug Bell 11 Aug '05

11 Aug '05

I am trying to use the PMC4 on the EPIA-SP ( vt8237 ) but can't write to the internal flash. I have code that can read and write successfully on a SST49LF004 installed in the top socket. However, when I throw the switch to the internal flash (PMC Pm49FL004 ) I can read the flash ID via the registers at ffbc0000 and 0001, but I can't read the ID via the typical jedec cycle. Interestingly ( or not ) I seem to read back the last byte written out in my code, e.g. a 0x90 0x90 is read as the ID … [View More]

Might be because there is nothing in the LB code that prevents the memory range occupied by the video ROM from being allocated to PCI devices. What I finally ended up doing is creating a wrapper .S file for my mainboard that pulls the video ROM into the compiled LB RAM image: .… [View More]

[LinuxBIOS] VGA support
by Stephen.Kimball＠bench.com 10 Aug '05

10 Aug '05

Could someone explain the different VGA options with LinuxBIOS? I've read the testbios FAQ items. This seems to be a utility program that can be run after the system comes up to initialize a VGA card. Then I suppose one could open an X window. Then there are several LinuxBIOS Options that mention VGA: VGABIOS_START PCI_VGA_RAM_IMAGE_START CONFIG_CONSOLE_VGA CONFIG_LEGACY_VGABIOS Some VGA options are more useful than others. For example, CONFIG_LEGACY_VGABIOS does not seem to … [View More]

[LinuxBIOS] LinuxBIOS Summit
by Ken Fuchs 10 Aug '05

10 Aug '05

What topics will be covered at the LinuxBIOS Summit? Will it be limited to technical issues and things that directly affect technical issues such as access to chip set specifications, NDA issues, new BIOS technologies and LinuxBIOS' competition, etc.? Is making LinuxBIOS as popular and compelling as Linux and GNU/Linux distributions a reasonable and desirable goal? Would support of operating systems other than Linux such as OpenSolaris, xBSD, Plan 9, and MS Windows 2000/XP be a reasonable … [View More]
