sis630 IPL read wrong number of SPD RAM type
by zhu shi song 15 Jul '04

15 Jul '04

(1) RAM type sis630 IPL.S read is not 04 I debug sis630 IPL.S, I find the RAM type value that IPL read is 01 or 00 for different RAM but not 04. But my RAM is definitely SDRAM. The code is: ........... movb $0x02, %al # Read the RAM Type (SPD byte 2) CALL_SP(read_spd) # of the dram on current DIMM. movb %bl, %al # %bl is 01 or 00 for different RAM,not 04 outb %al, $0x80 cmpb $0x04, %bl # If the RAM Type = SDRAM ?? jne no_sdram # no, exit ....... Is there any bug in the codes reading spd bytes? (2) for some Sis630 mainboard, docipl will hang. Linuxbios can't be executed. I think the RAM initialization procedure is as compatible as BIOS.

vt5426 can't detect doc millenium
by zhu shi song 15 Jul '04

15 Jul '04

Dear sir, I've got one mainboard named A6T. A6T uses the same VIA northbridge and southbridge as vt5426. I boot linux from the mainboard and insert doc2001 in the BIOS slot. Then run the following commands: insmod docecc insmod doc2001 insmod docprobe these commands can detect doc2001 successfully in SIS630 mainboard. But in A6T they can't detect doc2001. ( I check /proc/mtd file, it is null ). SIS630 need flash_on utility, does VT5426 need some utility? Who knows the cause? thanks zhu --------------------------------- Do you Yahoo!?

I've got QDIA6T mainboard see http://www.qdigrp.com. It use via 8601t and 686b. I try to boot it using vt5426 mainboard in freebios V1. After testing, ipl.S will loop forever in the following code(in src/northbridge/via/8601/ipl.S): ............ wait_for_flash_ready: /* delay by reding NOP register before polling the FLASH READY bit, this is inlined to save a call/ret pair */ movb $0xbb, %al outb %al,$0x80 doc_delay: movb %ds:0x04(%di),%ah movw $0x04, %cx # this one is DANGEROUS but I am # sure the upper 3 bytes == 0x00 0: movb %ds:0x20(%di), %al # read DOC NOP retisger loop 0b # four times testb $0x80,%ah # is flash ready ? jz wait_for_flash_ready ........ Anybody can explain me what the code work for? thanks zhu --------------------------------- Do you Yahoo!? Yahoo! Mail - 50x more storage than other providers!

I mean if you build tg3filoide_disk.zelf, it will confuse the Etherboot. So you can only build tg3filo.zelf or tg3ide_disk.zelf. Do you have spare IDE disk? If So format the disk into ext3 or fat format and copy the .elf file into it.

I was reading through the documents and came across this line in README.etherboot_in_filo: You can not use filo and ide_disk at the same time. Can you tell me what this means? Do I need to rebuild filo without IDE support to get USB support?

I then try uda1:/kernel initrd=/boot/initrd root=/dev/sda1 and I get those td errors. I then tried your ramfs.elf and I get the same behavior are my elf image with the CRC complaining when the initrd portion is executed.

This problem is odd. I can boot my elf fine with etherboot, but not with filo. I can boot my kernel fine with filo, but not the initrd. I can even boot your kernel of the ram.elf you sent me, but when it hits the initrd it fails with the same error as mine. I suspect either my filo is not configured like yours or that there is a problem loading a mulitpart elf (kernel & initrd in filo). I'm confused as to why filo didn't just use the etherboot portion of elf_load. It could be you were on the, "bleeding" edge? ;) Can you tell me how much memory you have in your working system? I have just one cpu and 512meg memory. Curious if loading it high & it runs out of memory or something like that.

FILO in TWO CPU version LinuxBIOS works well S2885 in LANL and my lab. So I still suggest that you get another CPU to verify the whole process.

I still think you might have a config problem here. Put some debug prints in the initrd code and try to zoom in better to what's going on. ron

The initrd is ext2. Tried changing the disk to ext2 and still get the same results. This did work, but is not what I need. 1. Etherboot the filo.elf (4.2) as a payload 2. Run the filo.elf 3. It is able to load my kernel & initrd.elf, only off of the hd, not the usb stick. Arg! My setup uses etherboot as a primary to get the kernel & intird as an elf. But if that connection dies I want it to use the kernel & initrd elf on my usb stick. This first part works just fine. It is finding a way to get the second part that is taking me weeks! :( On Tue, 2004-07-13 at 11:48, Peter Stuge wrote: On Tue, Jul 13, 2004 at 11:35:01AM -0400, David Aubin wrote: > Thank yo for the image, but oddly it fails exactly the > same way.... > Found initrd block 0 > crc error > > I'm using reiserfs, I'll try ext2.

question about via 82c686b, 82c686, vt8601 , vt8601t
by zhu shi song 13 Jul '04

13 Jul '04

dear sir, I've got one mainboard. Its northbridge is vt8601t, southbridge is 82c686b. I checked freebios source , there exists mainboard vt5426 which is very near my configuration. the northbridge and southbridge of vt5426 are seperately vt8601 and 82c686. Who know the difference between them? By the way , where can I get the manual of vt8601t and 82c686b? I have checked via website, there is no deep technical information about them. tks zhu --------------------------------- Do you Yahoo!? Yahoo! Mail Address AutoComplete - You start. We finish.
