/**************************************************************************
Etherboot -  BOOTP/TFTP Bootstrap Program
Intel EEPRO/10 NIC driver for Etherboot
Adapted from Linux eepro.c from kernel 2.2.17

This board accepts a 32 pin EEPROM (29C256), however a test with a
27C010 shows that this EPROM also works in the socket, but it's not clear
how repeatably. The two top address pins appear to be held low, thus
the bottom 32kB of the 27C010 is visible in the CPU's address space.
To be sure you could put 4 copies of the code in the 27C010, then
it doesn't matter whether the extra lines are held low or high, just
hopefully not floating as CMOS chips don't like floating inputs.

Be careful with seating the EPROM as the socket on my board actually
has 34 pins, the top row of 2 are not used.
