What's an "Imperial G" motherboard like, exactly? Any/all
details might be relevant. Does it have a socketed or
soldered-on bios chip?

Is it running what looks like the Imperial G bios or an HP
bios? After flashing, did you enter the bios and try
setting the boot device(s)?

I'd try disconnecting ALL non-essential devices and only
connect a floppy drive. Then I'd try disabling all boot
devices in bios except floppy. Then i'd try to boot and
watch the floppy access light... even if it doesnt' boot it
could be useful if it tried to access that drive.
If it tries to access the drive, you might be able to put
together an emergency recovery floppy that it automatically
accesses. What bios make (for example, Award, AMI, Phoenix)
and revision number (again, # for the bios core, not the
motherboard bios version, for example Award 4.51)?

Do you have the board manual (or can you get one)?
Such jumper would typically be in bottom right-hand area of
the board, if it's separate from the clear CMOS jumper. If
all else fails, use the clear CMOS jumper and/or pull
battery for a few minutes.
Note that if the bios EEPROM is soldered on rather than
socketed, this should be a last attempt, as clearing CMOS
might then result in it not POSTing at all. If the bios is
socketed and you have the correct bios, you can (or have
someone else) reprogram the EEPROM or provide that bios file
to a service which programs it into another EEPROM for you.
Then there's "bios hot flashing", Google will turn up info
on that.<!-- ~MESSAGE_AFTER~ -->
