?

Space is for a BOOTROM chip. Why do you feel you need this?
If the card is functioning ok dont worry yourself about it.

No, you can't. They take a standard 27cNNN EPROM chip and you'd need an
EPROM programmer to program it.

Do you understand the function of these eprom chips on network cards? It is
to boot up a diskless computer over a network, or to boot up and do a
network install of an OS.

Yes I understand.
My idea was, to build a firewall on a minimal and silent PC (say 486,
no HD, no fan, no CD, onboard video, maybe even onboard LAN ?)
and make the thing get it's Linux/IPTables stuff from another computer
on my local net.
So, it the firewall was compromised, all I'd have to do is find the
leak and reboot.

In which case you should consider the IPcop. Stick an old and otherwise
useless 1GB or so hard drive in it and use IPCop's transparent proxy
capability. I find it excellent on a network where multitude of PCs do
various software updates. The first one gets it from the net and the rest
from the proxy. Its amazing to watch a 20MB Windows update execute in just a
few seconds.
