That's simple to set if your network cards have jumpers on them. I used a pair of 3Com 3c509 cards. The first time I booted the machine, both cards came up at IRQ 10 and 0x300. Select a card, then auto-configure to have it choose a new IRQ and memory address. Do this for both cards, and remember to save the new settings.
Software Making the floppyfw boot floppy is simple.
Before you can boot it, you'll need to take it to some other machine and edit the config files. If you need to use another operating system, I understand you can edit these files with NotePad. You probably won't need to touch syslinux.cfg or modules.lst at all. So I'll discuss the main file, config . In the interest of clarity, I've stripped out most of the comments.
