Boot ROM
This card's boot ROM socket will take a standard 28-pin ROM chip. It has also been successfully tested with a 32-pin ROM chip using an adapter[1]. XTIDE will run without any problem.
The card's DOS drivers come with a configuration program (3C509.EXE) that can be used to enable the ROM socket (it is disabled by default) and set the base address, as well as adjust all the usual options like base address and IRQ.
