VGA
by Xavier Pegenaute 15 Jul '03

15 Jul '03

Hi, i have some questions about VGA in LinuxBios. If we don't use ADLO, there is'nt VGA Bios, then the unique possibility to see something in in Linux with the VGA is that we have implemented a FrameBuffer driver for the specific VGA board, and ofcourse that this driver has to talk directly with the hardware. And what about the Xserver ? the X software talk directly with the hardware ? For example if i want to mount a little computer in my home to see DVDs and Divx, is it possible with LinuxBios? Thanks. Xavi.

LinuxBios-help!
by Devi Priya 15 Jul '03

15 Jul '03

Hi, I am unable to understand many things here. I am using sc1200. External devices include 32 MB SDRAM, 4 MB Flash ROM, Ethernet, PCI audio/video decoder, FI1216-Tuner, LM4550-Audio codec, hard disk. I probably want to load linux from hard disk. If i want to use linuxbios for my project what are the things should be done? I dont use Disk on chip. Plz I have very limited knowledge reg this linuxbios. Help me to understand. _________________________________________________________________ Astrology can be fun. Find out for yourself. http://www.msn.co.in/Astrology/Astromagic/ With just a click!

DDR problem
by Andrew Ip 15 Jul '03

15 Jul '03

Hi, I'm testing 2 DDR from Samsung on EPIA-M, M368L1713DTL-CB0 and M368L1624DTL-CB0. Both of them are DDR266 128MB. The main different is M368L1713DTL-CB0 has 8x16MB IC's and M368L1624DTL-CB0 has 4x32MB IC's. So far, LinuxBIOS can boot flawlessly with M368L1713DTL-CB0. However, it fails when running ram test. Here is the log dump northbridge: 00: 06 11 23 31 06 00 30 02 00 00 00 06 00 00 00 00 10: 08 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 20: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 30: 00 00 00 00 a0 00 00 00 00 00 00 00 00 00 00 00 40: 00 18 88 80 82 44 00 00 18 99 88 80 82 44 00 00 50: c8 de cf 88 c0 04 00 00 6c 00 08 08 10 10 00 00 60: 0a 00 00 00 e6 32 01 20 c5 25 43 58 00 44 00 00 70: 82 48 00 01 01 08 50 00 01 00 00 00 00 00 02 02 80: 00 61 00 00 00 00 00 00 00 00 00 00 00 00 00 00 90: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 a0: 02 c0 20 00 01 02 00 1f 00 00 00 00 00 02 00 00 b0: 00 00 00 00 80 00 00 00 68 00 00 00 00 00 00 00 c0: 01 00 02 00 00 00 00 00 00 00 00 00 00 00 00 00 d0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 e0: 00 00 00 00 00 00 01 00 40 00 00 00 00 00 00 00 f0: 00 00 00 00 00 00 03 13 00 00 00 00 00 00 00 00 Done.

Re: K8 + 2.4.21 + Tyan S2880
by YhLu 15 Jul '03

Eric, Thanks, I change 8k to 40k and it works. Because I put the elf in hda1. In the Config of Ehterboot, I have set BOOT_FIRST=BOOT_DISK and BOOT_SECOND=BOOT_NIC. In the fallback track, It works great and if HD is not there is will boot from Network. About the normal boot, it seems there some problems. After change the cmos.conf. boot_option=Normal boot_first=HDD boot_second=HDD boot_third=Network Then corresponding to BOOT_FIRST it says that "Wrong index" ??? When the HDD is present, it works as touch pci_ide (find one HD and print "Wrong index")/ isa_ide/ pci_ide and load image from ide. And When the HDD is not present , it works as touch pci_ide/isa_ide/pci_nic and load image from ide. Is it because boot_first should be set Network fixedly? In the main.c of Etherboot, it only at state=3 and index=0 and type mismatched can print such "Wrong index", It is a bug in Etherboot 5.1.8.?

An ELF image within 8K from the start of the DISK. Imperfect but it works. Eric

Eric, I have tried to build the tg3--ide_disk.zelf and use it in fallback and normal but all failed. In fallback track: It said: Searching for image...................................<abort> In Normal track: It said: Wrong index I have use to cmos_util to change boot track and BOOT_FIRST=HDD and BOOT_SECOND=Network. When building tg3--ide_disk.zelf, I used BOOT_FIRST=IDE and BOOT_SECOND=NIC. What kind of image in HDD that eltherboot wound want?

Re: ppc linuxbios support
by Greg Watson 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. Also, have access to sandpoint 755. Let me know if I >can help. > >Thanks > >Ramkumar

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
