EPIA5000 & parallel port
by Hubert Denkmair 21 Sep '03

21 Sep '03

Hello again, linuxbios+filo works now on my EPIA, thanks to everybody who helped me :-) There seems to be just one more problem - Is it possible that the parallel port is not initialized correctly by LinuxBIOS? I need it for my LCD which is controlled by LCDproc. With my original BIOS, everything works smoothly - with or without kernel parallel port support. But with LinuxBIOS nothing happens on the Display, seems as if no data is written to the port. LCDproc doesn't complain at all, but that's no surprise since it does not get any feedback from the LCD device anyways. Additionally, seems as if a kernel compiled with parallel port support doesn't find it either: --- imaudo:/# echo "Hallo" > /dev/lp0 bash: /dev/lp0: No such device --- Thanks for your help, again! Hubert

flash_rom & epia 800
by Damien Charlet 21 Sep '03

21 Sep '03

Hello list, First of all thank all of you for this great work. I'd like to flash my epia 800 + bios savior with linuxbios. Un fortunately flash_rom doesn't manage to write correctly the rom image, even after numerous tries. I removed the prints statement in w49f002u.c (the chip detected) to see if that helps with timings, but it doesn't change anything. The version I use is last friday's CVS. I've seen that different people have had problems of the same type, how have you solved that ? thx Damien -- Damien(.)Charlet(AT pu-pm.univ-fcomte.fr) Doctorant UIN:78754463 Laboratoire d'Informatique de l'Universite de Franche-Comte FRE CNRS 2661 - Centre de Developement du Multimedia de Montbeliard Tel: +33-(0)3.81.99.47.76 damien.charlet(a)pu-pm.univ-fcomte.fr

It is working now, patches sent to Ron Minnich, but he wanted to do some cosmetic changes next week. If you are in a hurry, you can download it here, http://www.mikrosol.de/southbridge.c copy it to freebios\src\superio\via\vt8231\ http://www.mikrosol.de/setup_serial.inc copy it to freebios\src\southbridge\via\vt8231\ then recompile, flash and lcdproc should work now!

Homemade BIOS switch for EPIA boards (and others with 2MBit chips)
by Sven Luebke 21 Sep '03

21 Sep '03

Hi! I didn't find the BIOS Sa**our here in Germany so I made my own one. Of course this hack is nothing special, but perhaps useful for beginners! EPIA5000 owners don't have to modificate the board itself. Background: The capacity of the new flash chip is twice as large (4MBit) as the original chip, so we can burn a full BIOS in the lower part of the memory AND in the upper part of the memory. To choose between them, we use the highest address pin (A18). If A18 is low, the "lower" BIOS is selected, if it is high, the "upper" BIOS is activated (you need a reboot of course). I use this setup since 5 days and everything is working as it should. Please don't build it, if you do not know what I'm talking about!!! Use it at your own risk !!!! Installation: Take a AMD 29F040(B)-70 (you can find them on ebay) flash chip, bend Pin 1 (A18) in the other direction, as close to the chip as possible. Then solder an isolated wire to this pin, isolate this pin EVERYWHERE with a piece of tape (it's IMPORTANT, that it doesn't get contact with the PLCC socket pin, you can't bend it so close to the chip) and solder this wire to the "middle" contact (which connects EITHER to the left pin OR to the right pin) of a 3-pin-switch. Now you have to find a 5V and GND source, solder/connect two isolated wires to them and solder the other side of the wires to the two other pins of the 3-pin-switch. For other boards than the EPIA5000 you have to be sure, that the supply voltage of the flash chip (called VCC) is 5V, otherwise you have to measure it and search for a source equal to the measured voltage (!!!they have to be the same!!!). For the EPIA5000 you can use the "Modem wakeup" connector, take an appropriate plug inclusive wires and connect the other sides of the wire to the switch (that's what I did). If your board is powered on, TURN OFF YOUR BOARD NOW, insert the AMD flash chip (take out the SSF 39SF020A before :-) ) and make sure, that pin 1 of the flash chip has no electrical contact to the PLCC socket contact. Make sure that you soldered your switch as described above: Pin 1 of the flash chip has to be connected (through the switch) to EITHER VCC (for EPIA = 5V) OR GND. If everything was OK, you are ready with the hardware part. Reinsert the original flash chip, boot Linux, get the original BIOS file, replace /freebios/util/flash_and_burn/flash_rom.c with this one at http://www.mikrosol.de/flash_rom.c (it is the SAME sourcecode, but the size of the 29F040 is reduced to burn only 256KB), compile it, take the chip out while power is turned on, insert the soldered AMD chip, write the original bios to the flash chip (if you have an EPROM Programmer, use it, cause it is safer) and mark the position of the switch. Everytime you will switch to this position, you are booting the ORIGINAL BIOS. If you want to burn the other part of the memory, switch to the other side (while power is on and you are at the console) and burn it. Be aware that both parts of the memory are writable, so you have to check the position of the switch BEFORE you are flashing. Flashing at the marked position of the switch is only necessary, if you want to replace the original bios. That's all! Really helpful I think! Best regards, Sven

Sourceforge back from the dead?
by David Hendricks 19 Sep '03

19 Sep '03

Today, for the first time in months, I was able to successfully checkout an entire freebios tree with CVS! For those who have ben getting "connection reset by peer" errors, I'd suggest trying again ASAP while it still works.

about FILO ........
by gimyung han 19 Sep '03

19 Sep '03

I just tested FILO on my EPIA machine............ it works fine, buf I just want to confirm that the image to be use by FILO should be elf image ? (which was combined with kernel image by mkelfimage utility..) I mean, can't FILO can use kernal image to boot linux? I just want to confirm it. _________________________________________________________________ 전세계인이 함께하는 웹 메일 서비스인 MSN Hotmail을 만나 보세요. http://loginnet.passport.com/login.srf?id=2&svc=mail&cbid=24325&msppjph=1&l…

Help needed (LinuxBIOS & FILO on EPIA5000)
by Sven Lübke 19 Sep '03

19 Sep '03

Hi all! I tried to install LinuxBIOS in my EPIA board, but with no luck. I don't have a serial null-modem cable, so I can't see debugging information :-(. I read the HOW TO for EPIA boards and used FILO as payload, cause I want to boot from IDE. In FILO I edited the file "Config" and changed only: AUTOBOOT_FILE = "hda5:/vmlinuz" FILO compiles without problems and creates an ELF file, which is 34 KB in size. Then I edited the file "epia.config" (changed only "payload /root/filo-0.1/filo.elf"), ran the python script, executed "make clean" and "make" in the target folder and linuxbios compiles with no problem. I burned the file "romimage" into the flash, rebooted but nothing is happening :-((. I tried the same with extracting the VGA-Bios and creating a combined payload with no result also! Am I doing something wrong? I have three questions anyway: 1. In "epia.config" there is the option PAYLOAD_SIZE! Do I have to change it to the size of the "filo.elf" payload?? I tried it, but it's not working nevertheless... 2. Is FILO compatible with the ext3 filesystem? I am using it in my root partition, but read, that ext2 and ext3 are compatible! Is that my failure? 3. Is VGA support for the EPIA5000 possible in this combination? Thanks for your help! Best regards, Sven
