In this case, you might want to consider writing a driver that knows how to talk directly to the flash. This would let you use the parts of the flash that aren't holding the boot image to store parameter information. > BTW, Mike the PC/104 board that I am using is from Mesa Electronics > 4c27 which is using the Crystal CS8900 ethernet chip. Do you know if > anyone is working on a driver for this chip? Yes, I have a driver here waiting for me to obtain a suitable IBM ethernet card for testing. It's designed for the IBM Etherjet cards, but it should work Just Fine. Let me know if/when you want it, and I'll put it up for fetching. I hope to have the hardware involved next week. -- \\ 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
