[comp.sys.ibm.pc] Writing device drivers under MS-DOS

bv@nixctc (Burkhard Viehoff) (01/24/90)

My colleague Uwe needs detailed information about the interface between the
drivers and MS-DOS and where MS-DOS 3.3 stores the information about
the drivers.
His problem is to run device-drivers in expanded memory and to switch
among them. This technique would help  to save space in memory.

Any hints, contacts or even solutions would be  very much appreciated.
Thanks in advance.
