If your board implements the basic PC devices: UARTs, PIC, PIT
etc. then a standard RedBoot floppy should boot on it. If any of these
is missing, or in some way non-standard, then it might get hung up.

The dots imply that it is booting correctly via the BIOS. Does it
clear the screen? Does it print anything other than dots?

One possibility is that it is getting hung up looking for the ethernet
device. Try building a RedBoot configuration that does not have
ethernet support: disable CYGPKG_REDBOOT_NETWORKING.
