| 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. |
