I am looking for a way to do the above, on an old Intel PM24555 20MB linear FLASH card.
This is the kind of thing
The PM24555 appears to no longer be made but similar cards do exist. I can get the PM24555 cards easily enough; it's reading and writing them which is tricky.
I believe it may be easier under unix but I really want a windows (or DOS) solution.
Any suggestions would be much appreciated.
