Boot ROM

This card's boot ROM socket will take a standard 28-pin ROM chip.

The card's DOS drivers come with a configuration program (3C50XCFG.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. If used in an EISA board the card can be set to EISA mode by use of the utility and later configured by the ECU.
