For current Thincan (artecgroup/dbe61) development we are using our own designed dongles: - LPC connector (the cable shouldn't be longer than 5cm/2 inch) - Altera Cyclone FPGA as the control part - 16 MB flash: 4x separate 4MB banks; chosen by jumpers (I can have 4 separate booting configs( LB/kernel/initrd) in one dongle) - chosen flash bank is seen as 1MB at boot, switched to 4MB mode by LinuxBIOS. After that you can address that 4MB by FILO as [EMAIL PROTECTED] - 4 digit LED display (POST code display + selftest) - miniUSB (by ftdi chip) for the programming flash banks - python script as programming tool PCB is 8cm x 6cm, i have seen the case for that unit too :) As much as I know this dongle were made available with initial price ca. €90 (in small quantities). I'd expect that such a thing (with somewhat different design) can't be much cheaper. Indrek -- linuxbios mailing list [email protected] http://www.openbios.org/mailman/listinfo/linuxbios
