Preconfiguration Information
4 The 3C503 adapter uses the BNC or RJ-45 port (the non-AUI connector) as the
default if it cannot detect a device connected to the AUI connector.

Known Problems and Limitations
4 The IRQ depends on the I/O address set using the jumpers. For example, if you
configure the 3C503 or 3C503-16 at I/O address 0x250, no other devices should
use IRQ 3.
4 The 3C503 board has limited on-board memory, causing poor NFS performance.
To avoid this, use a 4-Kbyte read and write buffer size to mount the NFS software
over the 3C503 interface (see mount_nfs(1M)).
