3 The object files given here are sufficient to create the BIOS
4 for the IBM system. Some sources are given as examples for
5 OEM supplied device drivers. These sources do not necessarily
6 implement all the features described in the device driver
7 documentation. They have evolved in parallel with the
8 documentation, so some features described in the documentation
9 may not yet be present in the drivers. Below is a summary of
13 ibmbio.asm Main body of the BIOS.
14 ibmdsk.asm Floppy and Hard disk drivers.
15 ibmmtcon.asm Multi-screen console driver.
16 ansi.inc ANSI X3.64 terminal emulation.
17 bugcode.inc Module which implements debugging
18 prints. The routine PUTC must be
19 modified for other devices. See
20 also the file DEFDBUG.INC.
21 sys*.obj The SYSINIT program. No source supplied.
22 biosobj.mak Contains instructions for building the
24 bootpach.exe Modifies a V2.0 boot sector (on A:) for
25 the IBM to accomodate the larger BIOS.
