Good stuff that french toast :-) You can hit the list anytime. We'll see if we can't make sense of this or that. > But for now: > > > DLink, et al, are putting a 802.11b wireless card with antenna on > > Compact Flash. > > Sounds interesting. Do you have a link? > > http://www.dlink.com/products/DigitalHome/Mobile/dcf650w/ Well there are more peripheral connection types than I listed previously. There's PC Cards slots, Compact Flash compartments, and SmartCard reader slots. Take a look at the HP Jordana 720, which is listed as compatible with the Dlink 650W http://www.hp.com/cposupport/manual_set/bpia2316.pdf Down around page 112 or so it gets into the different cards and their connectors. Compact Flash devices come in Type I and Type II format, using the names that PC Cards do, but the format is obviously much different. CF devices were in general mass storage devices, and we learned that RAM and Disk drives are both mass storage devices. Making CF mass storage cards ATA compliant and PC-Card compliant means that they can interface easily.

Yes it is standard and one of the main selling points of all CF Cards, which are not PC Cards but are compatible with PC Card specs. > If so, why would that be? > Why would a wireless card be accessed thru an IDE driver? I'm not sure that it does. It may be that CF I/O cards specifically emulate something else. I have a hard time determining the exact answer to this. The CF specs are hard to get. I think I'll dig around some more and see what turns up. > I followed your AP link and hit a deadend on the ftp download. Which was that? The access point one?

Yes, but the CardBus bridge is much more complex because of the chores it keeps, where the ATA host controller bridge is mostly just a splitter and a buffer to the bus. > The reason I am asking these questions is that we build in house a > very compact thin client with an extra compact flash adapter on > IDE and I'd love to use this little box as a diskless router with an > 802.11 lan. It's perfect for that as far as I can tell. Just follow the booting from a hard disk documents, which all refer to ATA as IDE. > Anyway, thanx.
