There has been several threads on media other than floppies, however CDROM's have been the only other media that has provided hardware write protection that I am aware of at this time. The subject has always been hung waiting on another viable alternative that hasn't shown itself as of yet. > Can someone draw up a comparison between cf/sm and mmc with cost > considerations so that users know what options are available - maybe > even post it to the FAQ.

If they are bootable and provide hardware write-protect (ie... switch or disk-tab), there are *MANY* of us waiting for a success story! A good possibility is running a SM card through an USB muti-reader since someone has posted that they have successfully booted Bering with an USB reader. I'm short of the money to try it myself right now or I would play Devil's Advocate. If you check the archives ~6 months ago, I attempted to write protect an IDE HD with an in-line switch. My attempt was somewhat successful, but has not been duplicated with any other BIOS/IDE controller. I would not say that the result would be acceptable for production use, so this idea was dropped as well. If anyone wants to give the SM card/USB reader a try with the (available?) write-protected SM card, I imagine this would work. BTW, do you have a link for this card???
