Shared ISA and PCI slot
Gary Cousins
Hi,
I'm after a bit of info. My motherboard list its slots as 4 PCI and 3
ISA (1 shared). The shared shares a backplane space, does it also use the
same space electrically i.e. is it impossible to have an ISA and PCI
device in the shared slot? If the slots are the same electrically is
there any known problem under Windows 95 as using it as one or the other?
I ask this as my video card has been giving problems and it has just
occured to me it is in the shared slot, i may swap it over tonight.
Thanks in advance

Sharing ha only to do with the common backplane space!
if you have one card that don't needs the slot on the backplane you can use
both ISA and PCI at the same time!
You're problem with video card is, probably, a driver problem. Try to find
an upgraded version on the Internet.

A shared slot means that two card connectors on the motherboard share
the same back-panel opening. The ISA card and the PCI card actually
fit into separate connectors on the motherboard. There is no way you
can put a PCI card into an ISA slot or vice versa. The ISA card's
external connector panel is shifted to the right of the card (seen form
above) whereas the PCI card's external connector panel is to the left
of the printed circuit card. Some cards don't make us of the
external connectors panel.
I guess that in this case, it would be
possible to remove it on one of the cards and make use of all
the motherboard connectors.
Is this true ?

Yeah, this is true. Some of the older PCI IDE/IO controllers made use of
a 'paddle board' in addition to the HDD controller. Reason being, you
can't map serial and parallel over PCI. So, they used the separate
controller for the IO stuff. And my CMD640x used the shared slot
precisely so. little paddle shaped card stuffed into an ISA slot, with
the PCI card directly above it, using the shared slot.

Can't see why not.
