DOC vs. IDE
by Christopher Bergeron Oct. 23, 2002

Oct. 23, 2002

Can anyone give me advice on what will acheive the fastest boot time? My options are the LinuxBIOS coupled with a DOC root or with root configured on hda1 (IDE). I boot into X and I'll need standard modules loaded. I'd like to fit the entire install on a DOC but only IF I'll get a faster load/boot. Would a combination be faster or just DOC ? Much thanks in advance to anyone that can provide advice... -Chris Bergeron

nonsense C/H/S values for CF (used in ide)
by Q-ha Park Oct. 4, 2002

Oct. 4, 2002

I have a board with gx1, pc97317 and cs5530a with one ide slot. I've been booting linux with Phoenix bios so far with no problems, and I tried linuxBIOS to boot linux. but I noticed strange C/H/S values like "init_drive sectors_per_track=[768], num_heads=[768], num_cylinders=[768]". and it failed to boot. does anyone have similar problems like this? Phoenix bios sees the device and read the values correctly... thanks, Q

RE: No IRQ Known for interrupt pin A of device 02:04.0. Please try using pci=biosirq
by David Xiong Oct. 1, 2002

Oct. 1, 2002

The mainboard is K7SEM and irq_tables.c is already in the source tree. I run the program getpir and get an irq_tables.c file which is the same as the one in the source tree. The program util/getpir reports 6 slot found, whether I plug in the multimedia card or not, and produce exact the same irq_tables.c. And the option HAVE_PIRQ_TABLE=1 is set in the config file of the source tree. I traced into the kernel source and found that the original BIOS set IRQ when POST, but linuxbios does not do so. The IRQ is 0 when start up with linuxbios. When the driver of the multimedia card comes up, it find the card has not an IRQ. Then the driver try to get one from the irq_table, but the PCI device is not in the irq_table, so it can not find one or assign one to the device. What else can I do? Can I hard code one irq to the card? Thanks!

If this is a new board I need all the info so I can put it in the source tree. ron

Hi, what's the kernel patches that I can use for Via chipsets? /src/kernel_patches are mostly SiS based, and does actual SDR initialization works for DDR too? Thanks! CM.

OT: Diamond Stealth 64 DRAM PCI on Linux Framebuffer w/o Option Rom?
by Lee Sept. 29, 2002

Sept. 29, 2002

Dear LinuxBiosers, I'm afraid this topic is a bit off topic, but I thought you guys would be the best to ask as LinuxBios doesn't load option roms. I have a Diamond Stealth 64 Dram PCI card which I have removed the option rom from (and placed in an antistatic foam eprom case.) I want to use it for dual monitor support, but had to remove the option rom as it wasn't designed for multi-card operation. I am wondering if this thing can be used with Linux's framebuffer support?? My other card is a Nvidia GeForce2 64MB AGP. I figure I may have to assign it some settings, I'm not sure. I haven't put it into the target machine yet, but I have tested it booting with a Cirrus Logic 5422 w/ Option Rom on a different machine and it is detected by 95, but not used. Thanking you in advance, Lee Edward Causier.

PCI: No IRQ Known for interrupt pin A of device 02:04.0. Please try using pci=biosirq
by David Xiong Sept. 29, 2002

Sept. 29, 2002

I have Linuxbios boot from DOC successfuly. But I can not get my 2-channel-video-monitor-card up. When I load the driver, it shows PCI: No IRQ Known for interrupt pin A of device 02:04.0. Please try using pci=biosirq The driver can not get IRQ, and it can not work. If I boot from BIOS with the same kernel , the card can work correctly. I noticed that BIOS set IRQ into the card but linuxbios does not do so. Can you tell me what shall I do? Thanks a lot. David Xiong

PCChips M758LMR+
by Todd E. Johnson Sept. 29, 2002

Sept. 29, 2002

Hello folks, I have the PCChips M758LMR+, and I am extremely interested in this excellent project! Does anyone have example LinuxBios boot times with this board? While grepping for additional information to get started, I came across: http://www.acl.lanl.gov/linuxbios/config/index.html However, it does not contain this board, as well, I encounter a 404 when attempting to create a config for another board. Besides the FAQ, are there any other resources to help me get started with this system? Thanks in advance! Regards, Todd E. Johnson http://www.groomlakelabs/grandamp/ tejohnson(a)yahoo.com
