my question on the 8111
by ron minnich 18 Nov '03

18 Nov '03

mea culpa. Yikes, I forgot that in addition to the smbus interface on one function of this chip there is a full smbus set on the PM interface. Ooops. That makes much more sense now. ron

linuxbios V2 on epia-m?
by Dave Ashley 18 Nov '03

18 Nov '03

I'm interested in having this but there is only epia. Can someone outline the steps involved in bringing V2 up on epia-m? I might tackle it if it looks to be something I can handle. However last time I checked (yesterday) I couldn't even build the v2 epia though. Don't let my interest stop anyone else from jumping in and doing this. -Dave

question about amd8111_early_smbus.c
by ron minnich 18 Nov '03

18 Nov '03

Here's some enable code static void enable_smbus(void) { device_t dev; dev = pci_locate_device(PCI_ID(0x1022, 0x746b), 0); if (dev == PCI_DEV_INVALID) { die("SMBUS controller not found\r\n"); } uint8_t enable; print_debug("SMBus controller enabled\r\n"); pci_write_config32(dev, 0x58, SMBUS_IO_BASE | 1); enable = pci_read_config8(dev, 0x41); pci_write_config8(dev, 0x41, enable | (1 << 7)); /* clear any lingering errors, so the transaction will run */ outw(inw(SMBUS_IO_BASE + SMBGSTATUS), SMBUS_IO_BASE + SMBGSTATUS); } Sounds OK, right? here's what I don't get: #define SMBUS_IO_BASE 0x0f00 #define SMBGSTATUS 0xe0 #define SMBGCTL 0xe2 #define SMBHSTADDR 0xe4 etc.etc. The io base is f00. The SMB registers get added to that: you get fe0, etc. I can interpret this two ways, one of them being that the IOBASE is fe0, and the way this is written is to optimize romcc behavior. But then I don't get this part: pci_write_config32(dev, 0x58, SMBUS_IO_BASE | 1); I would expect this to be set to SUMBUS_IO_BASE|0xE0|1 so that that the IOBASE in the register is 0xfe0. Or something else is going on here and I am *really* lost. Somebody want to clear my confusion :-) ron

440BX and SDRAM
by Erik Jansson 18 Nov '03

18 Nov '03

Hi all! I have been playing with LinuxBIOS on motherboards with Intel's 440BX chipset. I have a whole bunch of them: a Microbits Epox EP-61 BXA-M, an MSI MS6120 (dual), an Intel development board and a custom designed BX board). I have managed to get most of the stuff up and running. Two things are missing though... 1. I can't manage to initiate more than 128 MB of SDRAM (ramtest fails). I've tried a lot of different types and brands of memories, standard DIMMs and SO-DIMMS, different sizes, etc. I'm thinking it has something to do with "double sided" memory (or dual "module banks" or whatever terminology you choose). Buffer strength settings maybe? But I've tried the same settings as the standard BIOS uses (which sets up the memory correctly btw) and still no go. Some obscure bit in some obscure register? 2. Dual CPU support on the MSI board. My major concern is the memory support though. I just thought that I'd throw out a question and see if somebody has been or is working with the same thing and has bumped into something similar. The archives tell me that there has been some fierce fighting with SDRAM issues earlier and I see why... This stuff is complicated. I'm running a LinuxBIOS from CVS dated 2003-11-04. /Erik -- ______________________________________________ Check out the latest SMS services @ http://www.linuxmail.org This allows you to send and receive SMS through your mailbox.

re: Missing files from freebios2

Chris, The S2880 can boot from the very beginning. Lsi_scsi.c is about onboard scsi support. I don't know if you really need that feature. I didn't get the permission from LSI to release the code yet. So if you really need that feature, I will send the pre-built image to you. Today I will verify the config can work without that file.

Missing files from freebios2
by maillists＠petrolhead.com 18 Nov '03

18 Nov '03

Hi, So my last question referred to S2880, however just noticed a Quartet build does exist, which is what I really want, saves me doing the port! What state is this port in at the moment? Does it boot, I'm quite willing to help out bringing it up. The freebios2 cvs tree seems to be missing at least; tg3.zelf lsi_scsi.c And more importantly for me /suse/stepan/tg3--ide_disk.zelf is missing, guess that's on Stefan's drive somewhere ;-) Chris

Inline assembler problems with S2880 build
by maillists＠petrolhead.com 18 Nov '03

Hi, I'm a newbie to this, but I'm trying to build for a Tyan S2880 board. However during the build I get; .... eebios2/src/devices/hypertransport.c /tmp/ccniyAWJ.s: Assembler messages: /tmp/ccniyAWJ.s:120: Error: Incorrect register `%rcx' used with `l' suffix /tmp/ccniyAWJ.s:122: Error: Incorrect register `%rcx' used with `l' suffix This is built on a completely standard Suse 2.4.19 build Linux Boco 2.4.19 #1 Wed Jun 25 21:34:14 UTC 2003 x86_64 unknown unknown GNU/Linux Any thoughts Many thanks Chris

Questions about LinuxBIOS
by Adam Nielsen 18 Nov '03

18 Nov '03

Hi, I've been keeping an eye on the LinuxBIOS project for a while now, and I've recently got hold of a couple of old motherboards I'd like to use with LinuxBIOS. I realise there will probably be quite a bit of work involved with getting them going, but I'd just like to check I'm on the right track first! I've read through all the FAQs, and I have a few questions: Since none of the boards have on-board networking, I'd really like to use LinuxBIOS to enable them to boot Linux over the network with a standard PCI network card - it seems possible, but there doesn't seem to be anywhere that gives a definite 'yes' to this with standard PC hardware. Once LinuxBIOS is compiled and ready to go, Is it possible to flash it into the board's existing BIOS? (Without any hardware modifications, ZIF sockets, etc.) One of the motherboards has a recovery jumper which can be used to reflash the BIOS if there was a problem during a flash operation, do you think this could be used as a backup option in case something goes wrong with LinuxBIOS? (yes, I'm aware of all the dangers etc., but the boards only cost me $1 each so I'm not too worried if I render them unusable, it'll just be a bit of a waste...) The reason I ask is that the flash chip on one of the boards is soldered on and physically very small. I did get hold of a BIOS upgrade for it though, and the BIOS code itself appears to be supplied as four 64K files - is this large enough? Sorry if my questions are very basic, I'm new to all this ;-) Thanks, Adam.

Re: epia-m (600mhz) -- /dev/ttyS1
by Dave Ashley 18 Nov '03

>perfect!!! Can you verify something: On my epia-m ttyS0 is 1/2 the baud rate it should be, so I can't get 115,200 baud, only 57,600. Can you verify if you can get 115,200 on both serial ports? -Dave
