Hardware-oriented CONFIG.SYS questions (apologies, this is old stuff but
I've forgotten it and I need the info):

On Intel-based machines the microprocessor is connected to the PCI bus.
Yes? (I think this used to be done with a north bridge - south bridge
chip set.)

OS/2 has kernel support for the PCI bus. There is also a legacy ISA bus
which is connected to the PCI bus, and OS/2 also has kernel support for
the ISA bus. Yes?

If you have a PCMCIA, SCSI and/or USB bus then those buses are connected
to the PCI bus and you need a PCMCIA, SCSI and/or USB bus driver to use
these buses. These are BASEDEV= drivers (for example BASEDEV=SYM8XX.ADD
for some of the symbios scsi bus chips). Yes? (Can anyone give me a
typical BASEDEV= for the PCMCIA or USB bus?)

Each device is connected to a bus and you need a driver for each
device. Each device driver is specific to a particular bus and device.
The device drivers are loaded after the bus drivers (otherwise the
driver can't communicate with the device because the bus isn't available
yet). Yes?

Are there any other OS/2-supported buses which I've missed? I mentioned
PCI, ISA, PCMCIA, SCSI, USB. I didn't include IDE because the IDE bus
control is actually done at the PCI level as far as I know (similar to
an LPT parallel port controlling a printer). There are lots of other
buses -- firewire/ieee1394, hpib, gpib, esdi come to mind -- but I don't
know if any have OS/2 drivers.

Thanks much,

- Peter
