I've read posts about the RD1 that suggest its integrated flash device is low quality and it may take 10 or more flash attempts to get a good flash update to the RD1 flash device. As a result, many RD1 BIOS Savior users will flash the commercial BIOS image (or other known good BIOS image) into the RD1 integrated flash device as many times as needed to get an image that boots. Then use the original BIOS device to flash test BIOS image (usually LinuxBIOS images among this group), since the original BIOS device usually flashes OK on the first attempt. I've used the RD1 in the above fashion with great success on the Tyan S2885 mainboard. The same RD1 would not work on the nVidia CK8-04 CRB mainboard. I think the CK8-04 CRB requires a flash device that the RD1 does not support. However, the RD1 worked well as an "do nothing" adapter which allowed swapping the BIOS flash device between my flash burner and the mainboard without any wear to the mainboard's BIOS socket. BTW, my flash burner is an older Enhanced Willem Universal Programmer. I got mine for only $60 US over a year ago. I've seen it for less than $40 on eBay a few weeks ago. The newest model is going for about $50 US. It does a LinuxBIOS flash in about 5 minutes; not bad for a $60 burner. However, it does require changing DIP switches to match an image for each device it can program. Great for the amateur or professional with a small budget. > > BTW, a cable of your RD1 is not broken? > > I needed soldering to fix it. > Mine was fine out of the box.

Magnani Sent: Tuesday, September 13, 2005 8:08 AM To: linuxbios(a)openbios.org Subject: [LinuxBIOS] E7501 Raminit rewrite This one ends up being a little more than a "patch". I ended up reorganizing the E7501 raminit code so I could follow it, and fixed some bugs along the way. Significant logical changes: * Added support for "fast" (64-clock) refresh * Added code to support remap window for 3 - 4 GB systems * Fixed premature configuration of true row boundaries that resulted in some sections of DRAM not receiving JEDEC commands (see http://openbios.org/pipermail/linuxbios/2005-June/011752.html). * Redefined RCOMP_MMIO so that RCOMP registers can be configured on systems where A20M# is asserted. * Disabled subsystem (vendor) ID configuration * #ifdef'd out suspicious looking code (see http://openbios.org/pipermail/linuxbios/2005-June/011759.html) * Added optional run-time checking of dual-channel compatibility of installed DIMMs * Move JEDEC SPD and SDRAM definitions into reusable #include files Probably, the rewritten code should be reviewed as if it were new. My hope is that it is now easy enough to follow that this shouldn't be too bad. The original code is, of course, in Subversion. Since I reordered the functions as part of the rewrite, a 'diff' of of the new code against the original won't tell you much. I've attached a reordered copy of the Subversion code that won't compile, but should be a little easier to diff against the new code so you can see what's changed. I will hold off on committing this for awhile to give people time to look at it. I know that radical changes are a pain to review, but IMHO the improvement in maintainability is significant. New files that are part of this 'patch', but not included here (I committed these to Subversion): src/include/spd.h src/include/sdram_mode.h src/include/northbridge/intel/e7501/e7501.h Thanks, Steve ------------------------------------------------------------------------ Steven J.

[LinuxBIOS] Does LinuxBIOS run on the ECS 760GX-M?
by Angel 17 Oct '05

17 Oct '05

On my search for a LinuxBIOS compatible AMD mainboard, I tripped over the ECS 760GX-M. It's socket 754 and uses the SiS chips 760GX and 964. As far as I know SiS is supporting LinuxBIOS actively, so in terms of the chipset the board should run LinuxBIOS. Plus, it has a 4Mb (=500 KiB) Flash ROM with the following description from the manufactorer's website: SYSTEM BIOS Award BIOS with 4Mb Flash ROM Supports Plug and Play 1.0A, APM 1.2, Multi Boot, DMI Supports ACPI revision 1.0 specification Because I want to be shure that this mainboard supports LinuxBIOS before I will buy it, I thought I'd better ask here if anyone has it in use and can say something about it. The chipset and the plug and play BIOS at least sound promisingly to me. Oh, and a previous ECS mainboard, the K7SEM, is proven to be compatible.

The x86 standard is now is tuples of (nodeid, coreid) which means on k8 based systems the cpu apicids will always be densly packed. I haven't seen the reference but I have been assured that is the way things are working. I believe it was Richard Breuner assured me of this In addition in the code cleanups that have been us only use the (nodeid, coreid) as supporting multiple form simultaneously is both confusing, and creates code that is hard to maintain.

RE: [LinuxBIOS] compiler error isolated
by Steve Magnani 28 Sep '05

28 Sep '05

This sounds something like the bug I reported in http://openbios.org/ pipermail/linuxbios/2005-June/011782.html. I notice in the revised spd.c file there are several if/else/else... constructs. I wonder if you would have better luck using 'switch' statements - when I have problems with 'if/else' statements, I've found that recoding as 'switch' makes the problem go away. See the latest e7501 raminit code. ------------------------------------------------------------------------ Steven J.

Re: [LinuxBIOS] romcc - Internal compiler error: Cannot find block dominated ....
by Doug Bell 28 Sep '05

The attached spd.c contains functions called from my raminit.c's sdram_set_spd_registers(). Raminit.c is #included into auto.c. I've tried various workarounds including putting all the code in spd.c under one function, getting rid of the device_t ctl, etc. but compilation doesn't yet work. Ideas appreciated.

[LinuxBIOS] Re: SMP hardware question
by Adam Talbot 28 Sep '05

28 Sep '05

Humm So AMD will not give out this info easily or free... Then let us find it. Test a system in both states (Single and Dual) and look at the differences. See if we can spoof the system into thinking it has two MP CPU's when we have two XP's in the box. The one question would be linuxbios support for the Tyan MPX board or something along those lines. -Adam Ronald G Minnich wrote: > Adam Talbot wrote: > >> Been over two years on this setup, no hardware problems, yet.

[LinuxBIOS] [Fwd: LB Summit Schedule]
by Ronald G Minnich 28 Sep '05

28 Sep '05

Here is the sched. Notice a few things. We have left a lot of time for discussion in important areas. We need discussion leaders in: o user friendly -- how do we make this nice for users -- they can't use boot cds! How do we make linuxbios useful for the desktop? How can we make it more useful for other types of users -- e.g. embedded? What works for users? what doesn't? o user interface Should it be open firmware, a la sparc and apple? bash? efi shell? what should it be? How should people interact with linuxbios? o developer friendly -- how do we make linuxbios easier for developers what makes it hard right now? How can we improve it? what is the biggest change you'd like to see? o development model do we need a Linux-like code vetting and approval process? how do we manage patches? Who will the gatekeepers be? how do we ensure that the code base stays pure? We need ideas. o developer friendly II (more discussion) fuse the previous two sessions and try to find the right ideas. o device object model, table gen What are we going to do about: ACPI EFI tables openbios strings etc. What (if anything) needs to change in the current device model to make this all work? o automatic build and test automatic build is possible, but test? how can we do that? can people contribute systems at their site so that, when a new version comes out, we can make sure it is tested? How far can we automate the process of verifying a new release of linuxbios? Can industry help with this? OSDL? o programmer's manual How can we create a manual for new programmers? o vendor friendly What are effective and ineffective ways to work with vendors? what's the value proposition for vendors? How can we interest more vendors in linuxbios? What's missing? o efi strategy How do we address systems such as EFI? Can we, for example, find a way to run EFI modules under openbios or Linux? o N-party NDA (or NDAs in general) How do we address the issues raised by 3-, 4-, and more-way NDAS? What I'd like is people to nominate themselves to lead a discussion. Optionally, several people can nominate themselves and we'll form panels, where people put forth a position (5 mins) and then we have discussion on those ideas. So, we're looking for YOU. Please volunteer. We've come a long way, but there's more work to be done. You can make the difference. Thanks ron
