Hallo,
does anybody have experience with DOC's on an Epia-M board? I read in a previous message ( http://www.mail-archive.com/linuxbios@clustermatic.org/msg03307.html ) that the DOC Millennium 8MB Module MD2802-D08 might work. Can anybody confirm this?
They also say I need a ZIF socket, which makes sense, and an DIP-32 256K X8 120NS Atmel Flash Memory. I don't really understand what I would need that for.
Can anybody help?
Also I read that the EPIA-M still has problems with some DDR-Rams. Does anybody have a list which Rams are supported?
thanks,
Michael
Hello from Gregg C Levine I might. The ZIF socket is for easy insertions of the part in question, which you have correctly decided. As for the Atmel part. Good question. I suspect that's the part number the boards are wearing. Not having seen one of them physically, I can only take a guess or three on this subject. First off, do you have the board where you are? Does it run Linux effectively? No complaints, et cetera? Suggest you post the output of the command, "#lspci -v", to this list, and we should be able to advise. (The command is the string after the # mark, the mark is the shell prompt.) ------------------- Gregg C Levine hansolofalcon@worldnet.att.net ------------------------------------------------------------ "The Force will be with you...Always."

i am currently playing with this. my epia-m has no DIP32 socket. i decided to use a DIP2PLCC adapter to use the MD2802-D08. so i can plug it directly into the bios socket.

i dont understand. you could exchange the rom ... but then there is no space for the MD2802-D08.

i am currently trying to use (mount;-) the the MD2802-D08 when plugged into the bios socket. this seems to be much more tricky then i thought. i've already written some test prg -- and it seems that the behavior of my DoC is very strange.

please remember, getting to work in the socket is the easy part. Getting epia support for memory up and running in 256 or so bytes is the hard part.

that is true. where can i get more info in how to init the mem on a epia-m? do i have to rev eng the bios?

read the linuxbios source, of course!

I think EPIA-M is even harder to fit into IPL.

Hi,
I think EPIA-M is even harder to fit into IPL.
why do you think so?
More steps are required to init DDR. It might not fit in 512 bytes.

oops, I forgot the DDR nightmare. I think DoC is out for EPIA-M.

Hi Niki,
what is so complex with ddr? could you send me / point me to some more info about init a ddr? or ask the guys at via?
It is the hardware limitation since the ddr init code probably does not fit in ipl area of DOC which is only 512byte .

yes. i got the point. but to be sure we need to know _how_ a ddr is initialized. so the question is -- who knows how to init a ddr?

It is already checked in. Checkout the memory init code under vt8623.

we do. It's all over the newer mobos.

look at the linuxbios ddr code ;-)

src/northbridge/via/vt8601/ipl.S is code that worked for the vt8601 2 years ago for DoC uses.
Not guaranteed to work with all DRAM. The 8601 is very tricky.

nwaibel@blade100-2 ~/freebios-20030910 $ for i in `find -iname "*ipl*"`; do echo $i; mpage -4fHl $i | lp; done
as you can see -- i am going to rtfm :)
i think that the CLE266 (epia-m) is quite different then the vt8601. right now i've no idea about northbringes, but i hope that will change soon :)
where did the ppl (who have written all the ipl.S files) got the information from?

doubtful, I have found lots of reuse of cores in these norhtbridges. But I'm willing to be convinced :-)

I wrote it. I got info from VIA. They were quite helpful about it.

so you know some guys at via already. may you ask them if the same code could be use in a cle266? or (if not) how that northbridge can be initialized?
