I stumbled across a parameter to add to the boot command line, after running setup again and seeing exactly how "hdb" is described in the partitioning setup. Or maybe I saw this description earlier in the boot up process, I can't remember:
This seems to identify the zip drive "partition" properly and boot proceeds normally.
I'm a bit hazy as to how I incorporate these extra parameters into my default boot procedure. I've logged in as root, and poked around in /etc, but I'm not having much luck at determining where or how I would insert this information.
I'd appreciate a pointer or two. Also do you think there is much chance of ever getting a Diamond Supramax 56k "winmodem type of modem" to work in Linux?
