[LinuxBIOS] chip vs device and enable / init explanation request
by Doug Bell 22 Sep '05

22 Sep '05

Can someone explain the usage of chip & device keywords in the mainboard Config file? Also can someone explain the invocation of __pci_driver ops like pci_dev_enable_resources? How should these ( and pci_domain ) be structured, i.e. would one list each chip (with its pci devices) and a corresponding 'end' statement ? It appears we have northbridge as the highest level (chip) block with everything inside, including chips such as CPU. However, I get multiple initialization of my … [View More]

CompUSA sells BIOS Post code cards for $50, we bought one and it was very useful during a certain stage of development. It'd help you before serial output is working. They have a 2 digit LED display, it's a little pci card that plugs into any pci slot. Within linuxbios and all bios' in general during the bootup process different codes are displayed. You can put in debug statements like post_code(0xda); to cause a specific code to show up. So you can tell how far it gets before something goes … [View More]

So your serial cable connection is right. I don't know who port the dk8s2, maybe ollie, He may send you one pre-built image.

And run init -q. After power cycle the machine with linuxbios.rom flashed, but I still cannot get output from serial cable. BTW, I connected the cable to another machine and can recieve serial output of booting process. BTW, I installed lxbios, and run it right after linuxbios.rom is flashed. But it said that that linuxbios is not installed. Does it mean that the linuxbios.rom generated is still incorrect? The way I flashed linuxbios and ran lxbios is below: -bash-2.05b# ./flash_rom -vw /home/opt/linuxbios/LinuxBIOSv2-2040/targets/Iwill/dk8s2/dk8s2/linuxbios .rom The arguments are: -vw /home/opt/linuxbios/LinuxBIOSv2-2040/targets/Iwill/dk8s2/dk8s2/linuxbios .rom Calibrating timer since microsleep sucks ... takes a second Setting up microsecond timing loop 454M loops per second OK, calibrated, now do the deed Enabling flash write on AMD8111...OK Trying Am29F040B, 512 KB probe_29f040b: id1 0x7f, id2 0x45 Trying At29C040A, 512 KB probe_jedec: id1 0xbf, id2 0x60 Trying Mx29f002, 256 KB probe_29f002: id1 0xbf, id2 0x60 Trying SST29EE020A, 256 KB probe_jedec: id1 0xbf, id2 0x60 Trying SST28SF040A, 512 KB probe_28sf040: id1 0x7f, id2 0x45 Trying SST39SF020A, 256 KB probe_jedec: id1 0xbf, id2 0x60 Trying SST39VF020, 256 KB probe_jedec: id1 0xbf, id2 0x60 Trying SST49LF040, 512 KB probe_jedec: id1 0xbf, id2 0x60 Trying SST49LF080A, 1024 KB probe_jedec: id1 0xff, id2 0xff Trying SST49LF002A/B, 256 KB probe_jedec: id1 0xbf, id2 0x60 Trying SST49LF003A/B, 384 KB probe_jedec: id1 0xbf, id2 0x60 Trying SST49LF004A/B, 512 KB probe_jedec: id1 0xbf, id2 0x60 SST49LF004A/B found at physical address: 0xfff80000 Part is SST49LF004A/B Programming Page: 0007 at address: 0x00070000 Verifying address: VERIFIED -bash-2.05b# lxbios -a lxbios: LinuxBIOS table not found.

[LinuxBIOS] Asking help for serial output
by Frank Samuel 21 Sep '05

21 Sep '05

Dear all, Pretty new to linuxbios. I worked for a week to try to get serial output of linuxbios but failed. Hope someone can help me here. I tried two motherboards, Iwill/DK8S2 and tyan/s2882. Compiled succesfully and get a linuxbios.rom and flashed them to chip using flash_rom. But I didn't see any output via serial port. Can someone tell me what could be the causes. Thanks in advance. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the … [View More]

How do you get the SATA 0 HDD to load using Etherboot-5.2.6 on a Tyan 2891. I've built a filo.zelf payload and using hde2:/ as the boot parameter but it's returning No Device found. Thanks /ed

[LinuxBIOS] BIOS Saver discontinued
by Jeff Carr 20 Sep '05

20 Sep '05

According to the manufacturer, they are out of the BIOS Saver's and do not plan on manufacturing more. I tried to inquire about what quantity was needed to get them to make more, but didn't hear back from them. This is disappointing. Either the PLCC package was designed to protect the motherboard socket, or it was designed to discourage people from doing bios work. It's horrible. Every time you remove the chip it bends the pins around. It's only a matter of time until the pins break off. … [View More]
