Identification flash on board ?

Identification flash on board ?

[martin.kula]

Hi

I have PC140 with DoC and a flash chip.
Can anybody explain me next lines from dmesg ?
---------------------------------------
Possible DiskOnChip with unknown ChipID FD found at 0xc8000

How can I identify the flash (not DoC)?
I can use it under (ms)dos ;-((. Can I use it under linux ?
I tried some drivers but I hadn't success ;-(

Have you any ideas ?

Thanks

Martin

Is this an 8MiB DiskOnChip, or do you actually expect the extra chips to be 
there?

Hmm... It's strange, my DoC has 24MiB (I have one DoC on board on
address 0xe8000).
.......

.......
I'm using this DoC, that's right.

But as I know I have 1 MiB flash integrated on board too.
The flash is Intel 28F800-B5 Flash (from board guide).
I can use it with (ms)dos.
Can I use it with linux ? How I do it ? Or I can't ?

Thanks

Martin
