sis630 ipl SDRAM initializtion make some trouble
by zhu shi song 16 Jul '04

16 Jul '04

I've got two kind of sis630e motherboard, one is winfast 6300 Max pro, the other is from ellite group. (1) for winfast 6300 I've burned one DOC2001 to boot it, for some SDRAM it works well, for some other SDRAM it can't boot, it hangup on jmp spl_vector(after my debug testing ). (2) for ellite board The same doc2001 chip which works well on winfast 6300 can't boot ellite board. It also hangup on jmp spl_vector. For some SDRAM it can boot linux, but linux will hangup at anytime. (3) conclusion I think IPL SDRAM initialization has some problem. So the SDRAM can't work stably. Who has sis630 manual? I can check if I can adjust the SDRAM control parameters. Or someone can point out what's the exact reason causing the problem. tks zhu --------------------------------- Do you Yahoo!?

I find winfast 6300 Max pro using Sis630e chipset. The problem of reading spd RAM type byte is also return 01 or 00 for different SDRAM but no 04. Is it a problem? thanks zhu --------------------------------- Do you Yahoo!? Yahoo! Mail - 50x more storage than other providers!

I just never had time. Can't ELF do alignments? If so then we can just create this table into a seperate section and tell the linker to align it properly or perhaps locate it absolutly.

Re: E7501 support in V2

Eric, When can you commit cpu releated changes in the public tree? Please advise if I could commit E7501/P62h2/82801EB-R into the v2 now or after you commit CPU stuffs.

In general it is a motherboard type decision. It is one of the rough areas in V2 right now. For the rest you can see why I am in the process of reworking the cpu initialization code. Eric

SiS 530
by Andrew Richardson 15 Jul '04

15 Jul '04

Dear All, I am new to this list and have been emailing Ron a few times about the SiS530. Ron sugested that I use FILO for my project and I have had a trawl around to find filo, and have downloaded a BZ from a fairly unreputable looking web site. Does anyone have the "official" website address at all? Also Ron said to configure LinuxBIOS for the 530, but I thought that it was not supported by the LinuxBIOS project. I understand (basically) the idea of having payload code (which is filo from your advice), but I think I may need some more explicit instructions: do I assume correctly that I need to flash my current 530 board bios with LinuxBIOS with a payload of filo and have filo point to boot off HDA1? Then this leads me onto another question: can I pull a bios chip from another PC and use that to flash LB onto to use with the 530, or are some regions of the BIOS chip un-writable and/or mobo specific? If the latter then would it not be safer to get a small DoC and flash that, as I only have one 530 Mobo. Thanks andy ___________________________________________________________ALL-NEW Yahoo!

Re: Serenade BIOS
by Tony Cheng 15 Jul '04

15 Jul '04

Hi Ollie, I finally got the AMD Seranade board and tried the Serenade Linux BIOS. But I've got the serial port message like following and doesn't have any VGA output. (Seranade board come with a ATI Rage VGA card), I suppose the current Serenade LinuxBIOS doesn't have the VGA support? The serial output has a lot of "POST: 0x00" message output at at beginning and ending make me think I probably missed something. The changes I did with the BIOS is very minor. they are: 1. option ROM_SIZE changed to 512K, instead of 1MB to fit my Flash Part size. 2. option MAXIMUM_CONSOLE_LOGLEVEL and option DEFAULT_CONSOLE_LOGLEVEL changed to value 7, instead of value 8, in order to build. (Follow your instruction) Any input would be appriciated.

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!?
