floppy disabled when P55TP4XE flashable
Lynd D. Bacon
of J5 my floppy drive is disabled. I get a "Floppy disk(s) fail (C0)" when
I try to boot. Apparently com1 is disabled also, since if I load Windows
it fails to find my serial mouse on com1. If J5 has 1 & 2 shorted, my
floppy and mouse function normally. I've left J6 w/ pins 2 & 3 shorted, as
per the XE manual.
I've previously flashed another .XE board, but haven't encountered this.
Anyone ever seen this prob? Suggestions will be appreciated.

Look carefully and you will find another jumper (JP4 or 7 ??)
"hard wired" right next to the one you changed, making three
sets of jumpers, one is for on-board I/O the other is for BIOS
protect/flash and one for ?? make sure you change the right one...
been there... as both my TP4XEG boards are slightly differant.

and JP6. (No kidding! And no, I'm not misreading the pin labels, either!)
I suspect jumpering 2 & 3 of JP6 was what messed up the fd and com port.
Can't tell from the manual what JP6 actually does. Guess I should have
been suspicious when I found 1 & 2 on both JP5 and JP6 jumpered to begin
with.

Take a closer look. I'll bet you are actually moving J4 which is the
onboard IO disable jumper (that's why the floppy disappears). On some
boards there are no pins for J6, instead a permanent jumper is
soldered to the board. this leads to you misidentifying J5 as J6 and
J4 as J5.

This is a very common error because the manual is poorly written. Look VERY
carefully at the jumpers. You will see that JP6 is hard wired and that what
you changed was JP4, which controls the onboard I/O. Disabling the onboard
I/O often causes the floppy to disappear. If you want to disable onboard
I/O, use the BIOS to disable COM1, etc.
JP5 controls the boot-block protection feature, but that only works if you
have an Intel BIOS chip. The SST BIOS chip does not use this feature, so my
guess is that you have the SST (look at the PFLASH panel to determine which
BIOS chip you have). If you have the SST, the position of JP5 is
meaningless.

You were setting both JP4 and JP5, not 5 and 6. JP4, 5, and 6 are all
together between two of the PCI slots. JP4 (the rightmost one from the
front of the board) enables/disables the onboard I/O controller, hence the
floppy/mopuse problems when you changed it. JP5 and JP6 are supposed to
be set to program the BIOS, however, JP6 is hardwired to position 2-3, so
you don't see a jumper cap there, and all you have to change is JP5 if
you're programming over the boot block.
It is possible to program the BIOS without changing JP5 if you're not
programming the boot block, or also if you have a 5V flash chip I believe.
There's a good bit on this somewhere on the Asus site in one of their
FAQs.
