### NAME

podulebus - Acorn Expansion Card bus driver

### SYNOPSIS

podulebus0 at ioc0 bank 4 (NetBSD/acorn26) podulebus0 at root (NetBSD/acorn32)

### DESCRIPTION

The podulebus driver handles the expansion-card interface in Archimedes machines and their successors. This includes conventional expansion cards, mini expansion cards (as introduced in the A3000), network expansion cards (as introduced in the A3020), DEBI expansion cards (as introduced in the Risc PC), and Mk II network cards (also introduced in the Risc PC). Drivers for individual cards attach as children of the podulebus device.

NetBSD includes several machine-independent expansion card device drivers. There are also some device drivers which are specific to NetBSD/acorn26 or NetBSD/acorn32.

### BUGS

Too few drivers are shared between NetBSD/acorn26 and NetBSD/acorn32.
