The Linux kernel can be built to have a minimal DHCP (or BOOTP or RARP)
client in it, which will query for an address via the local network

Look for "IP autoconfiguration" in network options. You'll need a few
other things compiled in too (driver for the NIC chip, AF_PACKET
support, etc).

The other way would be to use an initramfs with a userspace dhcp client
- you could even have modular NIC drivers this way.

Whether the dreamcast port of the kernel supports initramfs, and whether
its NIC chip driver can be compiled in (instead of being a module), I
don't know.
