BTW, the flash disk is access as drive=0x80, a hard drive. Are there any issues with boot1/boo2 accessing it as drive=0x80 ? do you have any ideas on how I can transfer the image over to flash? or do you still think I can use diskcopy? > > Yes, although I have 8MB Flash memory to play with. > > In this case, you might want to consider writing a driver that knows > how to talk directly to the flash.

Actually the flash is composed of two 4MB NAND chips soldered on the main board. And I can partition the chips as two separate 4MB drives. However, Mesa Electronics wrote their own BIOS support for them. I need to check with them if they are willing to give out the specs for accessing the flash chips directly. > > BTW, Mike the PC/104 board that I am using is from Mesa Electronics > > 4c27 which is using the Crystal CS8900 ethernet chip.

Great! Will it work with 2.2.6 Release ? I would like to try it out asap, I am trying to meet some deadlines for this project. I could do some test for you as well.
