hi,
it seems that more and more boards are using PLCC chips instead of DIP chips. (http://www.ioss.com.tw/web/English/RD1BIOSSavior/SelectionChart.html)
if DIP is used you can replace the onboard bios chip (normally 2mbit) by a 8mbyte (64mbit) (m-systems md-2800-d08 or md-2802-d08) DIP chip. that way you have the possability to put the kernel and a small rootfs directly into the bios chip.
why cannot you do this if your board uses a PLCC chip? are there no PLCC chips with larger memory available? what types of PLCC chips are used? from which companies?
hmmm - on http://www.epboard.com/ you can find a PLCC to DIP adapter.
i'd like to know if it is possible to use E32-0041 (PLCC-32 to DIP-32 IC Adapter) on a epia-m board with a MD2802-D08 doc (m-systems). it seems that these chips have capacities of 2, 4, 8, 12, 24, 40, 72 MByte!!!

you will have to write IPL code that can bring the chipset up in 256 instructions or less.

AKIAK, DoC doesn't come with PLCC package. This is the main reason we don't like a mb with PLCC socket.
I may be wrong but doesn't epia-m come with 2 sockets one for Flash the other for DoC ?

but there is this PLCC -> DIP converter from epboard. you can put the (dip) doc device onto that converter. then you can put it into the PLCC socket. see here: http://www.epboard.com/eproducts/protoadapter2.htm#PLCCtoDIPAdapter product number: E32-0041

i ordered 2 boards -- will tell you soon :) but i think there is only 1 PLCC socket. (maybe the older boards had a DIP socket...)

i am quite new to all this. could you explain a bit more -- or give me some hints to written documentation?
do you think it is possible to make that working?
do you think it will be easy?

Mine (Epia-M 10000) only has 1 PLCC socket for 2/4MBit flash (no idea whether more is possible)

I think only EPIA has that socket. IIRC, Snapgear has got the driver for doc mil+, but I havn't seen anything yet. We have used a custom made DIP-PLCC adapter to connect DOC on EPIA, and Linux is able to see the DOC with mtd. However, we haven't done anything further.

"custom made DIP-PLCC": what did you customize?
there is also http://www.epboard.com/eproducts/ezadapter.htm#DIP to PLCC Adapter product number: E32-0030 name: DIP-32 to PLCC-32 eZ-Reconfigurable IC Adapter which seems to be a pin reconfigurable adapter...
andrew, do you think that the DIP chips could work with such an adapter?

We have gotten a PCB design for this.

is it just pin switching, or is it more you have to do?

take a look at the sis630 ipl.S code to get an idea. Then study the via vt8601 code for ram startup.

not sure.

it's easier for some than others. For me, it's always hard.

Is Snapgear's code GPLed ?

Should be. Got this one from Linux Devices http://www.linuxdevices.com/news/NS9097179629.html

Yea, I saw it on the MTD CVS. Wondering how M-system changed their mind.
