Not as far as I'm aware. You would want to be compatible with FTL (Flash Translation Layer), which is based on M-Systems' TrueFFS, which is very tightly controlled. FTL was pulled from the PCCARD '95 spec (because of patent issues with M-systems), but their blurb says that it's now included. It looks like it's time for us to get a new copy of the spec (perhaps a subscription even). (I've checked in the stuff that Nate loaned me, and it's not there, sorry.) If you're interested in doing this, pester me again when I get back from Australia (try around the 20th or so) and I'll get onto it. We've been meaning to do this for a while now. -- \\ 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-mobile" in the body of the message
