Read 512 bytes from the image file, write to the first sector on the disk. Read the next 512 bytes from the image file, write to the second sector on the disk. Repeat. Use the BIOS int13 calls to do your writing. You'll need to query the BIOS equipment list for the geometry, (or ask the user). > > A slightly easier solution would be to get a PC104 IDE adapter, and use > > an old IDE disk to transfer stuff around. > > Actually the board has an IDE controller on it already.

Plenty of ways - put DOS on the IDE harddisk, use a comms program to download the image over a null-modem cable for example. -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-small" in the body of the message
