Because the IPL area in doc2000 can't be rewrited, DiskOnChip 2000 16M doesn't support linuxbios. You may use Doc Milliennium 16M. ========================== 263电子邮件－信赖邮自专业

help: about kesem & xwindows
by bendany 05 Mar '03

05 Mar '03

currently , i use a k7sem mainboard. it work's fine with linuxbios. I replace the the BIOS with the linuxbios+etherboot. now i want to use the Xwindows. i want a embedded movie player, since mplayer use the fbdev output, and can't play it full screen. (sometimes play VCD) so i want to use the Xwindows to play the movie. my host system is Debian unstable. i works fine when i use a normal BIOS. i have strip the system, and get a 14M base system . i test it under the normal BIOS , i works fine. But when i turn it into linuxbios, and start the Xwindows. i get a blank screen. :( what can I do next? can you give me some tips? Best wishes! bendany@TW

simple question on fallback/normal images
by Ronald G. Minnich 03 Mar '03

03 Mar '03

I need to build a bios for the clearwater with no fallback/normal images. Just a single image. I find myself unsure how to do this, I've not looked in depth at the fallback/normal build stuff. Is there a simple option so I can build an image w/o the fallback/normal stuff on systems like clearwater that are configured for fallback/normal? thanks ron

Question about DoC
by hcyun＠etri.re.kr 03 Mar '03

03 Mar '03

I have a dumb question about DoC with LinuxBIOS. Today, I have requested to port LinuxBIOS on EPIA-M board equipped with DoC module. Though I have ported LinuxBIOS to several boards, I have no knowledge and experience regarding DoC. The board have seperated 2Mbit flash for BIOS and 32MByte DoC connected to ISA bus. Therefore I want to put LinuxBIOS on the normal flash part and put linux on the DoC. My question is 'What should I do to do this?'. After reading some documents from M-sys and this mailling list about DoC, I'm a little confused. M-sys claim it is compatible with normal HDD and recognized as disk drive without any software. Then what is the problem when it comes with LinuxBIOS? If my understanding is correct, it has built in software driver which must be executed from the normal BIOS environment. Is that correct?. Then again, what should I do to fetch kernel from DoC. should I use ALDO or Do I need something like BDK from M-Sys? Any comment, help will be very thankful.

Flashroms of more tha 2Mbits
by Xavier Pegenaute 03 Mar '03

03 Mar '03

Hi all, is possible to find flashroms with at least 6 o 8 Mbits of Memory to substitute the normal flashrom ..?, i prefer don't use DoC ... if it's possible, why you use DoC ? by price, by the possibiliti of Disk ? These days i was asking for many things about LinuxBios ..., this is because i'm studing the possibility to make my final thesis over LinuxBios ..., my objective is enlarge the capacities of kernel that is running into flashrom, just like manage hardware directly, and other things ..., for this reason i need more space in flashrom ..., and understand rombios functionality ..., at the moment i only knew about Linux Kernel ... Thanks. Xavi.

building a single image ...
by Ronald G. Minnich 03 Mar '03

03 Mar '03

ok, it gets more complex. There are hard-coded constants which I'm going to need to try to make less hardcoded. Going offline for a while to work this out. ron

Suggestions
by Nathanael Noblet 03 Mar '03

03 Mar '03

Hello, I'm wondering if anyone has any suggestion of any boards that are supported by linuxbios and have AGP graphics, audio and possibly onboard network (though eventually I'd like to add wireless networking instead). In a small form factor, like a SBC type setup. If you do that would be great. -- Nathanael Noblet Gnat Solutions 4604 Monterey Ave NW Calgary, AB T3B 5K4 T/F 403.288.5360 C 403.809.5368 http://www.gnat.ca/

VxWorks boot
by Felix Radensky 03 Mar '03

03 Mar '03

Hi, folks After a break I'm back to my task of using LinuxBios to boot VxWorks and I have the following problem. As I mentioned in my previous posts, VxWorks loader insists on beeing loaded at physical address 0x8000. The loader image size is 576K, and when loaded to 0x8000 it overrides areas used by LinuxBios itself, so I cannot even reach the code in LinuxBios that jumps to kernel entry point. I have verified that 68000 bytes can be copied to 0x8000, but 70000 cannot. If I'm reading ldscript.ld correctly, LinuxBios uses memory at 0x4000 for its data+bss, heap and stack. My question is: how can I modify this file to allow loading of VxWorks bootloader. Any other ideas are also welcome. TIA. Felix.
