Framebuffer or standard VGA ?
by Antony Stone 11 Sep '02

11 Sep '02

Hi. I'm using LinuxBios on an SiS630 motherboard (PC-Chips M810L). Is is essential to use the framebuffer device for video output under LinuxBios, or can I boot it into a 'standard VGA' mode ? I tried changing HAVE_FRAMEBUFFER=1 to =0 and also removing it entirely from my config file, but I just got no video output at all - the serial port told me everything else was starting up okay though. If it is essential to use the framebuffer, is there any way to change the refresh rate, because I'm using an old monitor which loses the top & bottom of the screen (it doesn't have a vertical size control :-( ) when I boot under LinuxBios. Hope someone can help, Antony. -- This is not a rehearsal. This is Real Life.

Anybody out there know how to make the second IDE channel come up on this thing? On the pcm-5823 boards, the secondary IDE is never seen by Linux. I think there has to be a setting somewhere, I just don't know what! ron

Do I smell a bulkbuy?
by Lee 10 Sep '02

10 Sep '02

Dear all, I think I see a bulkbuy on the horizon. http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=2052117210 - Magtek Card Reader. The original sale said 40 available (http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=2052616875&rd=1) and there should be plenty left, though I haven't asked. I am interested in these and I think it sounds like an opportunity. What do you guys say? Lee Causier, over and out.

Trouble getting started.....
by Antony Stone 09 Sep '02

09 Sep '02

Hi. Can somebody tell me what I'm missing here please ? I've just started with LinuxBios after seeing it at the LBW workshop ten days ago, and I can't seem to get even to stage 1.... I have a PCChips M810LR motherboard, and I've fitted a ZIF socket to swap the flash Bios for a Millennium MD-2800-D08 DoC device. I've compiled a 2.4.19 kernel and modules (although I'm not sure I've done this correctly - I can't find any instructions on which MTD options I need to make this setup work), and rebooted with the new kernel. I've built the various tools I seem to need for the SiS-based motherboard. When I do this: 1. Remove Flash Bios 2. Insert DoC (brand new device, just purchased) 3. flash_on 4. modprobe doc2001 5. modprobe docprobe 6. dmesg I get this: Possible DiskOnChip with unknown ChipID 00 found at 0xc8000 Possible DiskOnChip with unknown ChipID 35 found at 0xca000 Possible DiskOnChip with unknown ChipID F6 found at 0xcc000 Possible DiskOnChip with unknown ChipID E8 found at 0xce000 Possible DiskOnChip with unknown ChipID 97 found at 0xd0000 Possible DiskOnChip with unknown ChipID 63 found at 0xd2000 Possible DiskOnChip with unknown ChipID FF found at 0xd4000 Possible DiskOnChip with unknown ChipID FF found at 0xd6000 Possible DiskOnChip with unknown ChipID FF found at 0xd8000 Possible DiskOnChip with unknown ChipID FF found at 0xda000 Possible DiskOnChip with unknown ChipID FF found at 0xdc000 Possible DiskOnChip with unknown ChipID FF found at 0xde000 Possible DiskOnChip with unknown ChipID FF found at 0xe0000 Possible DiskOnChip with unknown ChipID FF found at 0xe2000 Possible DiskOnChip with unknown ChipID FF found at 0xe4000 Possible DiskOnChip with unknown ChipID FF found at 0xe6000 Possible DiskOnChip with unknown ChipID FF found at 0xe8000 Possible DiskOnChip with unknown ChipID FF found at 0xea000 Possible DiskOnChip with unknown ChipID FF found at 0xec000 Possible DiskOnChip with unknown ChipID FF found at 0xee000 No recognised DiskOnChip devices found I *am* inserting the DoC the right way round :-) My /dev/mtd0 is a char device with major/minor node 90,0 Can someone suggest which I'm doing wrong, what I've missed out, or where I can look for instructions to get it right ?

82802ab support in the flash_rom utility
by Ronald G Minnich 07 Sep '02

07 Sep '02

A third party has verified that it works too. So if you can't get MTD to work on these crazy parts you can fall back to flash_rom ron

e7500 and ich2rom
by Ronald G Minnich 06 Sep '02

06 Sep '02

some output from printks I added: init_ich2rom Found: 0x8086 0x2480 ich2rom: set 0x4e to 0x1 ich2rom: val 0x4e IS NOW 0x1 ioremap 0xff000000 size 0x1000000 result 0xf886d000 it finds the part it sets the 0x4e register to 1 for enabling write hey! same register as the piix4e -- think this is a coincidence? it does the ioremap of the last (BIG) 16 MB of memory (WOW!) Then it does a JEDEC probe. Do JEDEC probes really work with this 82802AB part? They must have but ... Eric? ron

I can confirm that "HOT PLUG AND PLAY" works with 82802ab parts, even though they have CLOCK etc. that normal flash does not. ron
