Hi, [I wish to apologize for the crossposting, but AFAICS quite a few coreboot developers are not subscribed to the flashrom list yet. Followup is set to flashrom(a)flashrom.org and I'll make sure your replies will be whitelisted and end up on the flashrom list.] flashrom has reached a state where pretty much all hardware access is now done in an OS-independent and hardware-independent way. Does flashrom still work on non-x86 architectures? I remember people using it on non-x86, but only PPC is mentioned near flashrom/flash_and_burn. Endianness might be an issue with the current code, but since I lack the hardware, I have no way to test. Please send any test/compile results as reply to this mail, and I'll try to address any bugs/problems as they turn up. Thank you! Regards, Carl-Daniel

HELP: Porting i830 RAM init to 440BX, now it won't compile

by Keith Hui

Hi, I need help getting this "patch" to compile. This is my attempt at porting Joseph Smith's i830 RAM init code to 440BX. Apply this patch and you have my 440BX part of the code. Which is where all the trouble is. I changed motherboard target to P2B-F, P3B-F (both of which which I haven't touched), and my under-development P2B-LS targets and they all fail. I need to figure out why romcc won't compile this. I wrote some stubs that I use to test this code under userspace with dummy SPD dumps from a dozen of my DIMM modules. I define TESTJIG when I'm compiling raminit.c to use these stubs for my own userspace testing. gcc is used to compile both my stubs and raminit.c for those tests and they all compile and seems to run fine. Now I need to boot test it. This code needs some expansion for i440bx because it supports a number of features not present in i830. Below are output of make when I tried to compile: ramtest.c:6.0: warning: Replacing undefined macro: CONFIG_SSE2 with 0 ramtest.c:56.0: warning: Replacing undefined macro: CONFIG_SSE2 with 0 raminit.c:605.46: raminit.c:789.32: romstage.c:96.32: 0xd28680 or Internal compiler error: non dominated rhs use point 0xd288d0? make: *** [/usr/src/coreboot/build/mainboard/asus/p2b-ls/romstage.inc] Aborted The part of raminit.c that croaks is: ... if (value == SPD_MEMORY_TYPE_EDO) { edosd |= 0x02; PRINT_DEBUG("EDO"); } else if (value == SPD_MEMORY_TYPE_SDRAM) { edosd |= 0x04; // <<< ABORT! PRINT_DEBUG("SDRAM"); // <<< ABORT! } ... Let me add another few questions here. I want to add code to have coreboot talk to the clock chip to find out its FSB in order to select the fastest memory timing from SPD data. 440BX only has official support for 100MHz, but they often are taken to 133MHz and beyond - my two boards are tested stable to 140MHz. I know the clock chip sits on SMBus, and have a fixed address at 0x69. That's with the clock chip my board uses. Where should this code be placed? The vendor BIOS placed the PIIX4E power management device base port at 0xE400, and its SMBus base port at 0xE800. Coreboot has its SMBus base port at 0x0F00. If I want to change the base port to match vendor BIOS, where should it be made? Any help appreciated. Thanks Keith

For programmer it would probably be simplest to use another mainboard which is compatible with flashrom. Can we remove BIOS with the machine turned on? Meaning: We boot with the good one, we remove it, we insert the second machine chip and flash it. Does it work? About the compatibility, I have a motherboard with a socket that has a award BIOS, is the chip/socket the same for AMI? Are they compatible? I'm sorry for the "noob" questions, but I don't really know much about BIOS. Check which flash chip is in the system, if it's an SPI chip then your best bet is to order the sockets from bios-repair.co.uk instead, I haven't seen SO-8 sockets easily available anywhere else. //Peter

However, the chance of getting everything working on the first try are zero. The chances to get the system at least to boot on the first try and always keep the system in a working, updatable state are almost zero, too. So if you attempt to port coreboot to this machine, you will need to create some kind of recovery mechanism. You could solder a socket to the mainboard, or a plug to reflash the machine externally. However, to get started, I suggest that you find out what flash chip you have on the board, so you can determine what recovery mechanism is suitable. (The flashrom utility from www.flashrom.org will help you with that) Also, a dump of superiotool -ed will help you a lot. Does the machine have a serial port? Stefan The machine has no serial port. I think it's a socketed bios(from the pics of the disassembly tech manual). However I have to disassemble everything in order to acess the BIOS Is there a way to plug a chip that has a wire coming to the outside to a machine that contains or the BIOS chip or and emulation of one? I'll do all the dumps, etc and post here again.
