Re: What PCI specs will I need?

Conn,

The first thing to ask is what you want your bios to do? If you are
making an adapter card,
it will be much different than if you are. Linux for mot and IBM  have a
pretty complete pci scan.

We will be building a small system that was two (mabey three) mini-PCI
slots.

IBM supplies an open bios that also scans the PCI and does some setup.

1)will you have fixed devices on your device.  This makes pci setup much
simpler.
2)pci is not that hard if you have a fixed number of devices.  A
generalized pci scan
  is very difficult.

Our system will only contain devices we choose to stick in it, so mabey
a complete scan isn't needed.

Heres a books you can get from amazon.com

PCI System Architecture (4th Edition) -- by Tom Shanley, et al; Paperback
PCI & PCI-X Hardware and Software (Architecture and Design) -- by Ed
Solari; Hardcover

Do either of these books contain all of the electrical characteristic
details ( such as impeadance, capacitiance, bus loading, etc) ?

By the I work for IBM and have extensive experience with the 405. I have
not worked with
the Mot parts but to fair, I have very good things about it.

The IBM 405GP is not out of the running yet. If they had one with PCI,
an SPI, an I2c, two serial ports, and two 10/100Mbps ethernet ports it
would have won hands down for our aplication.

You can get hardware questions answered about the 405 by contacting
ppcsupp@us.ibm.com

Thats handy.

MontaVista does the linux for both.
