I need a bit of help here. I have an application that I would like my XT clone to run from eprom. Ideally, I would like to put my application where the old rom BASIC use to reside. Many bios's still will try to boot BASIC if there is no disk in drive A:. I would like a similiar situation with my application. When there is no disk in drive A:, I want the system to run my eprom program. What I need to know is how to make my program look sufficiently like BASIC that the rom based checking routines will pass control to it. Has anyone done this or can you point me to articles where this is discussed? - John
