Re: [ECOS] redboot on i386 serial ports

[Reed Lawson <reedlawson at yahoo dot com>]

Thanks for the help, however, after rebuilding with
the enet disabled, I still only get a bunch of dots
(well, exactly 80 dots). Are they coming from redboot?
I see no dots when DOS boots. I tried to find where
the dots were printed, but no luck.

Where do I start troubleshooting? This is "suppose"
to be a standard 386 PC, but I'm starting to doubt
since it obviously has no floppy controller. they are
playing some tricks somewhere to get the flash to look
like a floppy. Its General Software embedded BIOS.

So, where do I start? What kind of hardware does
redboot assume is there in the 386 config?
(besides the enet that i disabled).

Thanks!
