That depends XP, Can you try with NB and the MB without any VGA onboard or addon card?

[LinuxBIOS] Booting windows XP
by Narahari, Narasimhaiah (IE10) 17 Aug '05

Hi, Have any body tried to boot "embedded XP with console redirected to serial port" using LinuxBIOS (freebios + ADLO bochs)? Is it possible to boot XP with the LinuxBIOS that has no VGA support? Please help me with this respect, With regards, narahari

Hi, Yes we are using ADLO bochs bios. We do not have VGA support in our bios yet. Is it necessary to have VGA bios support to boot Windows XP? The windows XP image we have has console redirected to serial port. Please help me in this respect, With regards, narahari

[LinuxBIOS] Where to put datasheets in wiki?
by Jeff Carr 16 Aug '05

16 Aug '05

I did lots of digging today to uncover what documentation I could find on the M-Systems MD2802. I"m still just assuming that is what I have in this machine because that's what flash_and_burn reports. Is there somewhere on the website links to the datasheets should be put. It takes a long time to track them down. It would be more productive if we pool the effort. Datasheets that available without NDA (most of them are nowdays) most companies seem to have a rather liberal view on putting them on other websites. I'd be of the opinion that we should just upload them to the linuxbios wiki. That way we know the document will stay around. Lots of these companies change the URL's over time so you have to start the whole process over again. In addition to the actual PDF, a link to the original site can remain also just incase the documents upstream are updated. Then again, maybe uploading the PDF's isn't worth the effort? The "Supported Chipsets" page seems like the right place to put the data sheets and other documentation known about a specific chip. Jeff

[LinuxBIOS] Booting windows XP
by Narahari, Narasimhaiah (IE10) 16 Aug '05

16 Aug '05

Hi, I am using the ADLO bochs bios, itself. I have an XP image directed to serial console. The redirection is done at windows level, i.e. after the windows is loaded. Is it very essential that I have to have VGA support in the BIOS to boot this kind of image? I am sending you the log which describes the details of the problem. Please find the log as an attachment.

[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 problems?

[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 hard to believe.
