Eric, S2880 is 2P and it is ready. S4880 is 4P and it is on-going.

The mapping which specifies which resources go where is on function 1. > I will add something at northbridge/amd/amdk8/coherent_ht.c There are some peculiarities as the code is a first pass at properly factoring it. I think I made a good stab at it but the code still needs to be generalized. An important thing to not is that when the code is done there should be no board specific hard codes, excpet in code that lives in auto.c Do you have a 4P case or just 2P? Eric

Re: power connectors for mainboards

I also have a need for multicomputer (motherboard only) ATX power supplies. Chances are we aren't the only ones, so perhaps it wouldn't hurt to suggest such a product to a high quality power supply manufacturer? My requirements don't necessitate the motherboard being able to turn off it's power. Within the next 6 months I expect to need: 20-60 units : At up to $30 / computer When I have the budget approved for them I'm thinking of contacting PC Power and Cooling to see if they're interested. Their Turbo-Cool 425 ATX/ATX12V in 12-31 units is on sale for $125.74 each right now, and its rated at: +5V @ 40A +12V @ 20A -5V @ .3A -12V @ 1A +3.3v @ 40A +5VSB @ 2A (With +5 and +3.3 combined < 300W) They're very conservatively rated power supplies, and I've never had one fail, (even in the most brutal environment I know of on computers schools.) The only power output limitation I see for the purpose is the 5VSB power. Some NICs (particularly Gigabit, and older 100 Mbs ones,) draw more than that for the WOL. But as the computers are diskless I don't have a need for that feature. How many quad output power supplies do you expect to need?

Eric, Thanks for the advice. I will try to add the SMP support in the northbridge/amd/amdk8 at first.

Or at least work with the others working on it and it can be a cooperative venture. Basically it is the nature of open source if something isn't implemented you can wait or you can write it. So far what I have seen is a talented user figuring out LinuxBIOS. I have not seen a developer giving constructive giving constructive feedback or helping in the development. My general advise to people who want to just use the Opteron port is stay away. For developers the advice is dig in, just be aware everything is undergoing active development, and there are a lot of pieces that have been stubbed in but have not been written correctly yet. SMP support is one of those. Eric _______________________________________________ Linuxbios mailing list Linuxbios(a)clustermatic.org http://www.clustermatic.org/mailman/listinfo/linuxbios

Eric, So If I want to SMP support, I have added the corresponding code by myself at this time.

So step you will add SMP support via MACRO define. ( CONFIG_SMP and > CPU_NUM ). Is it right? Something like that. Picking what to do next really depends on which pieces make sense, for the individual developer. An added complication is that we are busily performing some pretty significant cleanups in the code base. And so sometimes we get some pretty significant changes going on.

Thanks Alex. I am trying to find a way to build these low-cost for educational and tutorial uses. Anything custom is pretty much out. But thanks for the idea. ron

Eric, Yes, I'm reading the CPU documentation now. I found the code in northbridge/amd/amdk8 seems only support single node now. So step you will add SMP support via MACRO define. ( CONFIG_SMP and CPU_NUM ). Is it right?

There are a lot of hard codes that need to removed, in that code. It is only appropriate for developers wanting to improve it.

Beyond that if you get to the point where you are actively working and contributing this I would be happy to synchronize with you. Until that point all I can say is that the code is coming along, but the code is quite a ways from being general purpose yet. Eric

Ron, I have tried the romimage in AMD solo 7 MB, and the LinuxBIOS can boot until Etherboot. So the ROM image I built should be OK. The Tyan s2880 has two CPUs and supported dual channel DDR. The Opteron CPU is for Server/workstation and The cpu for AMD solo is for desktop (Crawhammer). Any advise.

I'm not sure what's wrong here. You may have to start checking the object code to see if it is correct. For what it is worth the new config tool is almost working ... just trying to get the sizing of the romimage correct. Hopefully I can start paying attention to linuxbios itself soon, now that I can bulid it. ron _______________________________________________ Linuxbios mailing list Linuxbios(a)clustermatic.org http://www.clustermatic.org/mailman/listinfo/linuxbios

The newest LinuxBIOS developer is Stefan Reinauer, who has been a supporter for years and is now heavily involved in K8 development (along, of course, with Eric Biederman). Welcome, Stefan! thanks ron

The assumption is that you could install Linux on the motherboard. lspci command is a Linux utility, which gives out the pci/device details. You may need to type it from root and send it across. See man lspci on Linux or google for lspci on web.

super micro P4DPR-IGM

I know there is a port for the super micro P4DPE but I need to know if there is a port for the P4DPR-IGM mb on the e7500 chipset And where I can find it.
