[comp.sys.ibm.pc.misc] Writing EPROM based programs for XT's

jpq@laue.ms.nwu.edu (John P. Quintana) (03/05/91)

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?
