Re: ppc linuxbios support
by Greg Watson 13 Jul '03

13 Jul '03

Hi Ramkumar, Ports to new boards, or suggestions on how to make the PPC code more modular and robust are always appreciated. You might want to start by getting linuxbios booting a linux kernel on the 755. This shouldn't be too difficult, as the 755 appears to use the same northbridge as the 7410. I used the MontiVista linux as it was already ported to the Sandpoint, though I had to make a few patches to get it to boot with linuxbios. Let me know when you get to this point and I can send you the patches. I've just ordered an EP405PC from EmbeddedPlanet which will be my next port. It uses the IBM PPC 405Gpr chip which is sufficiently different to the 7410 to be challenging. Hopefully this week I'll have the PPC version working under the new configuration system (check out freebios2 instead of freebios). This is going to allow us to build a static device tree which can be passed to linux. Heiko Schick and I have been discussing the possibility of mapping this device tree to an Open Firmware device tree that can then be used to boot linux on an OF system (such as Power Mac's). Stefan Reinauer has reminded me that we should work with the openbios community on this, though looking at the IEEE 1275 spec (all 250+ pages) I think they've got a big job ahead. :-) Cheers, Greg >I would be interested in helping out in the testing/development of >the PPC BIOS.

Linuxbios, bugfix in sis flash_rom
by Felix Kloeckner 12 Jul '03

12 Jul '03

Hello, after wondering why flash_rom wasn't working, i found that the compiler did some optimization on the reading/writing from/to the flash. So i made the variables for accessing the flash 'volatile', now it works! could you apply the patch to the linuxbios cvs? thanks Felix Kloeckner ps this patch is for jedec flash only, other parts probably have the same problem

Re: K8 + 2.4.21 + SuSE 64-bit mode + Arima HDAMA + 49LF040 + MTD
by YhLu 12 Jul '03

12 Jul '03

Eric, I switch to RH preview AMD 64 to build the kernel now the MB can finish the booting. I also try to boot local HD in normal boot. I use hda1 to store elf ( Kernel+RAM disk). But LinuxBIOS seems don't recogonize the elf format. And failed. I have use tg3.zelf to substitute the elf in the HD. LinuxBIOS can load it from HD and execute it. Any idea to produce ELF for HD booting. Or LinuxBIOS now only support 23bit elf? Regards Yinghai Lu

ANN: arima hdama boots...
by ebiederman＠lnxi.com 12 Jul '03

12 Jul '03

I have finally gotten all of the hard codes out of the memory initialization code and I can get the Arima HDAMA dual Opteron motherboard booting. And I have checked in the code. There is a lot more to do including cleanup of the code that works but one major piece is done. Eric

freebios2 and $Id:
by ebiederman＠lnxi.com 12 Jul '03

12 Jul '03

Unless someone has something to say in defense of the $Id: construct I am hereby banning it from the freebios2 tree. It makes it a pain to maintain a secondary CVS tree in sync as there are multiple unnecessary hits. Didn't we already ban $Id: ? in freebios2. In any case a huge lot of them had slipped in and I have removed all of them from the tree. And I intend to keep doing that when ever I find more of them. Eric

Any EPIA etherboot success stories?
by David Hendricks 11 Jul '03

11 Jul '03

I see a lot of people here have gotten LinuxBIOS working with the Via EPIA using an IDE device, but has anyone managed to get it working using etherboot to boot a kernel over a network? I'm a hopeless newbie and have been struggling with this for some time. I have links to logs, my payload, and my config below (Trying to keep the list archives tidy). I had gotten etherboot working with the PCM-5823s earlier and compared the minicom log with that of my Epia. The only real obvious discrepency I see is the entry point. The Geode entered at 0x00094000 (606,208), while the Epia is trying to enter at 0x00020000 (131,072). I'm using CVS versions of Etherboot and LinuxBios. However, I haven't been able to update in the past one or two weeks due to Sourceforge's problems so I might have missed an important patch. Links EPIA minicom log (High verbosity): http://www.flagen.com/~sc/linux/funstuff/epia-dave My Rhine payload: http://www.flagen.com/~sc/linux/funstuff/via-rhine-ebcvs.elf My config file: http://www.flagen.com/~sc/linux/funstuff/epia.config Geode (Elfboot part only): http://www.flagen.com/~sc/linux/funstuff/geode-elfboot-dave TIA --David

Where to buy the a Matsonic MS7308E
by Heinz N. Gies 10 Jul '03

hi i read your nice sis630 howto, after i finished ther are stilll some questions at first a very essential problem: where to get such a 'Matsonic MS7308E', i googled for it but only fins ome sides i japaneso or some language wich i can't differ as dumb european ;) and the side from ledtech where i don't find a suplier too :( so if someone know where to get this fine mainbords to but a LinuxBIOS on, please tell em :D secend question: did i realy need this FIZ if i wrrite the FlashRom in the same machine i want to use it? (cause it is very expensiv ... and i am just a poor student) third and fourth question: did i need an additional flashrom or can i use the buildin bios as flashrom and (i read that with an 4mb flash it is possible to put the whole boot proces in it) is possible to get a larger rom (and what is a n approx. price for such a 'ting') please excure my bad englsh thx Heinz N. Gies
