[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 southbridge. Also, how are these related to the chip_operations .enable_dev functions, and device_operations functions such as .init? We have made much progress on the Via EPIA-SP but these are some of the lingering questions. Doug __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

RE: [LinuxBIOS] Asking help for serial output

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 wrong or whatever. Have you tried all the serial ports? Maybe linuxbios is bringing up a different serial port as the console output one. Most MB's have more than one.

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.

About the serial console, did you verify the connection by enabling serial console on /etc/inittab?

Flash_rom? Did you try flash_rom -vw linuxbios.rom How many memory on MB? >4G or not? Linux Kernel version? 2.6, 64 bit?

[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 best spam protection around http://mail.yahoo.com

[LinuxBIOS] Using SATA HDD

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. Despite being careful with a small screwdriver and even using a PLCC chip puller. Fry's only has one and it's not well designed. I don't fish so I don't have fishing string for that other seemingly troublesome trick. It would be helpful if there was a chip socket that could be pulled straight up with one's fingers. Perhaps there are enough engineers and interest that we could cleverly design such a device (or something else ingenious) and have a bunch of them made? Along the same lines, has anyone tried using different size SST chips? I tried to duplicate the 256KB bios by putting it in a 512KB chip (SST 28SF040A vs 39SF020A). This didn't seem to work (no beep or video but didn't try port 80 parallel card yet). Perhaps someone knows if this should work. Can someone recommend a good place to get a handful of SST 39SF02A PLCC chips for these experiments? Thanks, Jeff
