The following program from PC Magazine of July 1988 will print the
12 digit ethernet address of a 3COM 3C501 Ethernet card.
It doesn't work for my Western Digital WD8003Es, or D-Link DE-001s
(NE-1000 clones).
The 3C501 uses IRQ 3, I/O base address 300H, and DMA channel 1.
The D-Link uses IRQ 3,I/O base address 300H, and no DMA, with a Base Memory
address of D0000H.
The WD8003E uses IRQ 3, I/O base address 280H, and no DMA, with a Ram Buffer
I/O Base address of C4000H.
These are the factory default settings of the cards.
Can anyone tell me exactly what this program does, and what I need to change to
make it work for all three cards?.
In a similiar vein, our primary Network is a 3Com. The drivers for each card
are loaded as devices in the CONFIG.SYS file. Is there any way of making
a universal boot floppy, that would load the correct driver for the card?
Any suggestions appreciated.
Aengus.
