I 'repartitioned' the flash: 256kB for the BIOS extension, 1.5MB for DOS and the remainder for Linux. The linux partition was formatted with JFFS. Everything seems to work find although JFFS makes a lot of noise when mounting the partition, moreover it finds only 13MB free and df only reports 4MB free... The next logical step would be to make the flash bootable by overwriting the BIOS extension. I'm a bit reluctant to do this as I don't want to make my board unbootable. E.g. what happens if there is something wrong with the new BIOS? Can you prevent somehow the BIOS on the board from executing the BIOS extension in the flash? Another question: why is the BIOS extension area soo big as the extension itself is only about 14kB? The autoexec.bat file on the Arcom bootfloppy mentions that the extension was enlarged some time ago to 256KB in order to accomodate the Windows CE registry???
