elfboot
by Xavier Pegenaute 10 Jul '03

10 Jul '03

Hi, any one can help me with this ? I was thinking that after crt0.S in ROMBASE (0x80000 for Matsonic) copy the LinuxBios (the payload) into DRAM (RAMBASE 0x4000 for Matsonic) follow the code to hardwaremain() initialitizing all hardware and arrive in write_tables that prepare the memory to let information about the hardware to the next O.S., and now we can choose between: 1) We want start an ELF binary (not payload) that is in DoC (p.e.) after LinuxBios. Then we execute elfboot() that look inside the ROM for the next code starting with a valid ELF header, build the segments, copy the segments and give the control to the program. No problem in this case, i think. 2) We want start a Linux Kernel that is recorded (neither payload) after LinuxBios binary in DoC (p.e.), then we execute linuxbiosmain() and in the end of this function we make a long jump to 0x90000. Here, i don't see what function in linuxbiosmain() copy the code of Kernel to DRAM.Any one know it ? Thanks. Xavi.

Sourceforge and CVS
by McMechan, James W CIV 09 Jul '03

It may that the CVS delays ~24 hours are a result of external pserver requests/ViewCVS being routed to the backup CVS system, it appears that SF is trying to organize for a hardware upgrade, and is providing direct connections to the main servers only when logged in via SSH, anonymous connections are being deferred to the backup server farm which has the ~24 hour delay. http://sourceforge.net/docman/display_doc.php?docid=2352&group_id=1#cvs see the message from 6-19-2003. They also have a August target date for the new hardware. Also while I still can't access CVS due to firewall issues I did download the automated daily snapshot tarball from http://cvs.sf.net/cvstarballs/freebios-cvsroot.tar.gz It does not appear to have been updated since Wed July 2,2003 16:50 was that the last checkin or is something else broken at SF, but still it is much more recent than that 2001 tarball I had before.

Hi All, Ron, I have been using linuxbios with sis730 motherboards (K7SEM and M810LMR) and I am having several systems "freezes" using 256MB sdram sticks (but none using 128MB memory sticks). Also I haven`t been able to use memory in the second memory banck (DIMM2). Linuxbios just doesnt sees memory in DIMM2. thanks for any feedback

intel 440bx unshadow for doc2001
by roger 09 Jul '03

09 Jul '03

Figured out from scanning through the openbios/devbios code on howto unshadow the intel 440bx to be able to successfully load the MTD doc2001 module and have it successfully detect the DOC. The devbios/openbios project can be found here: http://www.openbios.info/download/index.html And the url is at the bottom of the page for http://www.openbios.info/bin/devbios-0.3.2.tar.gz Does anybody know if any of this is already in the MTD drivers? This code unshadows and gives access to many bios devices. Went into the openbios/devbios/pcisets.c and commented out the two statements within the "static void intel4x0_deactivate(void)" function (this prevents the unshadowing after the bios.o module is loaded -- and while i was at it, uncommented the a printk debug statement). Loading the bios.o module shows the isa bridge info: Jul 9 02:40:27 BIOS: host bridge is 8086, 7190, 0 Jul 9 02:40:27 BIOS: isa bridge is 8086, 7110, 38 Jul 9 02:40:27 BIOS: isa bridge cfg is 0x64 Jul 9 02:40:27 BIOS: isa bridge cfg is 0x64 Jul 9 02:40:27 BIOS: isa bridge cfg is 0x64 (last line repeated many times) Jul 9 02:40:27 BIOS: 0k flashchip (ID 0x5f1f) found at physical address 0xfff01000 (va=0xd8854000+0x101000). Jul 9 02:40:27 BIOS: Probing PCI device with 256k rom Jul 9 02:40:27 BIOS: Probing PCI device with 64k rom Once I unshadowed the intel 440bx, the following script loads doc with ease: #!/bin/bash modprobe doc2001 modprobe docprobe doc_config_location=0xfff00000 cat /proc/mtd modprobe nft If i'm correct, the unshadow code just needs to be written into MTD for everything to work easily? mm...guess i should post to MTD mailing list. -- Roger http://www.eskimo.com/~roger/index.html

EPIA-M 10000 is also working with current epia-m code
by Andrew Ip 08 Jul '03

Hi, Just wanna confirm that EPIA-M 10000 is also working with current epia-m code, although both of them use different northbridge(vt8623 and vt8633). Here are what is missing on epia-m - enabling flash so that flash_rom can run - VGA support patches are welcome. :) -Andrew -- Andrew Ip Email: aip(a)cwlinux.com Tel: (852) 2542 2046 Fax: (852) 2542 2036 Mobile: (852) 9201 9866 Cwlinux Limited Unit 202B 2/F Lai Cheong Factory Building, 479-479A Castle Peak Road, Lai Chi Kok, Kowloon, Hong Kong.

DIP / PLCC
by Niki Waibel 08 Jul '03

08 Jul '03

hi, it seems that more and more boards are using PLCC chips instead of DIP chips. (http://www.ioss.com.tw/web/English/RD1BIOSSavior/SelectionChart.html) if DIP is used you can replace the onboard bios chip (normally 2mbit) by a 8mbyte (64mbit) (m-systems md-2800-d08 or md-2802-d08) DIP chip. that way you have the possability to put the kernel and a small rootfs directly into the bios chip. why cannot you do this if your board uses a PLCC chip? are there no PLCC chips with larger memory available? what types of PLCC chips are used? from which companies? -- niki w. waibel - system administrator @ newlogic technologies ag
