1/************************************************************************** 2Etherboot - BOOTP/TFTP Bootstrap Program 3Intel EEPRO/10 NIC driver for Etherboot 4Adapted from Linux eepro.c from kernel 2.2.17 5 6This board accepts a 32 pin EEPROM (29C256), however a test with a 727C010 shows that this EPROM also works in the socket, but it's not clear 8how repeatably. The two top address pins appear to be held low, thus 9the bottom 32kB of the 27C010 is visible in the CPU's address space. 10To be sure you could put 4 copies of the code in the 27C010, then 11it doesn't matter whether the extra lines are held low or high, just 12hopefully not floating as CMOS chips don't like floating inputs. 13 14Be careful with seating the EPROM as the socket on my board actually 15has 34 pins, the top row of 2 are not used. 16***************************************************************************/ 17 18/* 19 * This program is free software;
