As for the AGESA Equivalent , there isnt one. Intel just use microcodes although hardware specific limitations like the TDP support of the motherbaord will prevent you installing some processors (Obviously the CPU SOcket type has to match too!)
Can I safely get rid of raid_or? I will probably never use the 8212F's IDE raid.
Quote:Nope, the TDP doesn't matter. What matters - is the socket pins being changed when Core2 was implemented. Thus preventing Core2 CPU from starting on old boards. But anyway the BIOS must support Core2 and microcodes are not enough.
A thing to work out? Smile
So here's the question... Why would a 945P board not be able to electrically support the Core2 chips? And if so, how could the later 945P boards support the Pentium D and the Core/Core2?
Also another thing which I'm confused about... You say microcodes are not enough, that the BIOS must support it - can you elaborate?
In any case, what command would I use in CBROM to remove raid_or or the Foxconn logo?
Because the socket is not wired correctly to the chipset for it. For instance,if you look at socket m and socket p,they are similar. At first,it looks like just two wires are different. But if you look closer,there are a bunch more connections that were changed. So,for instance,you cant put a socket P cpu in a socket M board. I too thought if it was just microcode and perhaps a couple wires different I could make it work. For instance,I could perhaps cut the two pins off,and with some clever use of epoxy and conductive ink,add some tiny traces,then a layer of epoxy insulation,then epoxy new pins in place and connect them in reversed order. It would be intricate and tedeous,but would work,for two pins. But there are dozens of pins that are off,usually by one or two spots. So its not practical. I breifly considered the idea of making a little circuit board,wtih a grid of solder balls,that swapped all the right pins,then soldering the chip to the socket,then soldering the socket to the board just like any other BGA chip. But ultimately the one thing I cant do is increase the memory. Well,ok,I have a lenovo t60,which runs core bios,so I bet if I was clever I could. I bet I could do some sort of thing where I could bank select rows on a pair of 4gb simms or something,calling an exception handler to deal with it. I understand that System Management Mode can do things completely independant of the OS. I bet you could make it transparant,but if not,you could at least make it work in Linux. But then I realized,cool as it would be to have a core quad (heck,might as well go for broke) and 8gb in a T60 (uber geek cred there) I have better things to do with my time,and I have laptops with those capabilities already.
Another crazy idea I thought of was 16gb of DDR3 in my HP-G71. The idea is that the G71 uses a G45 variant chipset. As such,it supports both DDR2 and DDR3. I have not looked too hard (once again becuase I realized,I have a life,and a job,and enough projects like my old truck im fixing up) ,but the idea was that all the lines from the chipset to the ram are probably used for both types of ram. As such,maybe I could make my own SODIMM PCBs that would fit in the sockets. I could likely route any additional connections if need be. Then I would have to figure out something to do with the BIOS. Thats the worst part. The idea was,to do the undoable. Find a laptop that was similar enough,and hack its bios. The idea is,if I have the schematics of both laptops I could perhaps track down and spot the differences in the chipset initialization and using a lot of patience figure out the changes needed to get he new bios to work. In fact,if I were REALLY lucky,I might find one that already did! But once again,I realized its a lot of time,and a cool idea,and I might have done it 15 years ago,but now if I really really want a 16gb laptop Ill go buy one.
Oh,then there was yet another crazy idea along the same lines. Get a 1st gen macbook bios. Then try to figure out what is different in the hardware of the early macbooks and my t60. Same chipset. Prob different support chips. But the initialization is understood (coreboot supported). If I could actually get the thing to boot off a macbook bios,it would be the ultimate hackintosh. But then I realized,I have a job and a life... and if I want a macbook,Ill go buy one.
Then I thought,I bet there is some laptop out there thats virtually identical to the macbook. If I look far and wide enough,I bet I could find one. Once again,job and life.
Still would be fun to have a Thinkpad that natively booted OSX.
Actually,I thought of using Coreboot + EFIboot and and merging the stuff from one of the Hackintosh loaders into it... but you know what I realized after thinking about it a few minutes. (Yea,I have a lot of interesting ideas)
But I am trying to get the G71 to use a E8135 CPU. That either will work with a simple bios hack or not. Actually,Im considering the idea of a core 2 quad in it if the E8135 works well. The problem is the motherboard schematics show the board has some parts that have to be populated differently for the quad cores. Most of them are for the debug port so Im not sure of those will actually be required. But some are for the AGTL+ reference so those will be needed. Im guessing thats why so many people try the quads in laptops not made for them and they wont work.
