Hi,
I've experienced local mail delivery problem yesterday for an hour and
missed a few messages that might have concerned my posting of the use
of DiskOnChip.
Here is a summary of the experiences that I have with using M-systems
DiskOnChip product.
1. It is a chip that you plug into a CPU card that supports it.
2. It's capacity ranges from 2-144MB (?). The one that I used is 72MB.
3. It comes formatted with FAT but M-systems has Linux binary
driver for working under a few versions of Linux kernel including
2.0.33.
4. It only supports single partition in the current driver.
5. After following their documentations, I was able to have the system
boot from it.
6. It is easy to reproduce the content of the chip onto another chip.
They've provided DOS tools to read and write the whole chip.
As far as crash testing of systems is concerned, the DickOnChip system
did crash since I used it as a regular EXT2 file system. I used another
system to switch its power supply at a 60 seconds interval while it is
doing file copying after boot up. When file copying was removed, it did
not crash after power cycling for a few hours.
You can get the driver by sending request to [EMAIL PROTECTED] or send me
an email, I will forward the driver to you.
