Re: Smart/Dumb box again...

Hi Brian,

Not at all! I think it's great that Linux is getting into the embedded
systems market! We were thinking about Qnix (sp?), as a possible
replacement. We'd like to get a real time operating system, although it
would mean total rewrite to take advantage of it. Royalty free would be
good, we currently license DataLight's DOS. We load drivers for Socket
Services and TFFS (m-sys), a driver for SRAM cards, (if present), and
hopefully ATA cards. (And This morning I found the reason the ATA card
was not "listening" to my commands!)

Thanks for the URL's, I'll check them out (then I'll HAVE to do
Linux!). My BIOS doesn't support int 13h (floppy/hard disk), we rely on
the PCMCIA. Would Linux be able to use the TFFS driver? Or a DOS-style
block memory device driver? Interesting.

Thanks for the info
