Stefan, I'm porting Tyan S4880 now. I found that the following building err, do you meet it in AMD board? Even I only enable the CPU0's memctrl in the auto.c objcopy -O binary linuxbios linuxbios.strip gcc -o buildrom /home/yhlu/xx/xx/freebios2/util/buildrom/buildrom.c ./buildrom linuxbios.strip linuxbios.rom ../../tg3.zelf 0x10000 0x18000 linuxbios image is 65854 bytes; only 65536 allowed Linuxbios input file larger than allowed size! Regards YH.

Help on epia-m 10000 linuxbios VGA
by Santi Mirenna 27 Nov '03

27 Nov '03

Hi to all, today i make EPIA-M 10000 rom image. i compile to have VGA and Filo, after apply patch of Dave Ashley and info from Takeshi about RAM ammount VGA now is found by the system but .... In attach you have the output log .... Can someone tell me where i wrong? Dave Ashley reply: You haven't applied all the patch, specifically the handler for the unsupported bios interrupts. This is the bug where it just gets into an endless loop of bios interrupts, so the program needs to exit the bios somehow. -Dave Hi , can some one tell me where to look .... i made the patch ....where to look Dave to know if the patch is ok ? Thanks. Santi Mirenna

sc1200 with linuxbios possiblility?
by Deya 27 Nov '03

27 Nov '03

Hi, I am a newbie to this list. I like to use linuxbios for my project. I have sc1200 chip. I would have the BIOS program, linux kernel and file system in the same Flash memory (32 Mbit). Is it possible to use linuxbios to boot the linux OS from Flash to sdram though BIOS program, linux kernel and file system all existe in the same flash memory? I dont have a seperate Bios chip. Any suggestions on this would help me to proceed further. ________________________________________________________________________ Yahoo! India Mobile: Download the latest polyphonic ringtones.

Re: Fwd: ACPI support in LinuxBIOS - moderator approval (fwd)

I'll raise the question to the next level.... Has there been any discussion of putting any power management support into the LinuxBIOS. I've got a possible need for some basics, like suspend to RAM. Classic APM might be enough and simple to implement. ACPI would be a good choice, but I'm not sure about how much ROM foot print would be needed.

Re: send me your message directly: Dokumentation for creating LinuxBIOS for DL smartModule P5-266 (fwd)

Second, is there any documentaition how to build BIOS for Digital Logic´s smartModule P5-266? I´ve started to read the HOWTO/EPIA and HOWTO/L440GX and then to do according to the discriptions in this two different ways. But well, ... you guess, I wouldn´t write to the list if I would success. EPIA-HowTo uses etherboot and L440GX-HowTo boots without any ethernet connection just from the local disk. That´s what I would preffer also. As I saw there is a patch file in src/kernel_patches/ \ linux-2.4.17-smartcore-p5. So it seems to be the way of L440GX-HowTo. Is this correct, that I have to use this way to build the BIOS? How it was done by you? I´ve also tried to compile etherboot-5.2.2 and I got in src/bin-directory many of files compiled. As I know, on smartModule there is Intel 82559ER Ethernet controller and normaly we use the eepro100.o kernel module for communication. So I think if I would use etherboot I should use for "payload"-entry of the config-file eepro100.ebi. But ... in the mean time there were changes in etherboot and this compiled files are maned eepro100.o, eepro100.img and eepro100.zimg. Which of them should be used in config.etherboot file? Are there any prerared romimages for smatrModules around? I would like just to flash it into the EEPRM and to see the behaviour. Btw, I´m using the development kit of DL with two EEPROMs on it. One for core BIOS and second for VGA-BIOS. It is also possible to set the jumper either to boot from smartModule or from development kit. In this case it is a perfect tool to flash BIOSes (with phlash utility). Thank you for reading and answering my email. Benjamin
