Flash Card problems (and solutions)
Ok, so I managed to buy 4 linear flash cards from ebay. They are Centennial 2MB devices. The alios site gives brief details of how to load alios onto a card, so I thought this would be easy!
I have a hp omnibook 6000,with redhat 7.3 so I tried to use this to program the cards - no luck! Kept getting lots of 'cannot allocate memory' errors and segmentation faults when writing!
After lots of messing around, I got it to work as follows:
One note: I could not use the method specified with the alios source. Instead, I generate a 2MB image on disk, then write the whole image to flash, using a 128Kb block size. This works fine.

After lots of messing around, I got it to work as follows:
- Rebuild the 2.4.18 kernel, with PCMCIA support disabled
- Get the stand-alone PCMCIA package from sourceforge.
- Build this, then modify the /etc/sysconfig/pcmcia file to use the standalone PCIC controller, rather than yenta_socket

From the top of your head, do you think it would be possible to use an 8Mb flash card, and write a block size which will still allow the same image size to be uploaded?
I can't seem to get a hold of 2Mb Flash cards at the moment.
Any help you could give would be great!
Excellent work!
Many thanks,
Stephen.
