NOTES ON MEMORY MANAGEMENT
4.1 Problems Loading into the Upper Memory Area
Some computers with hard disk controllers, specifically bus master DMA
controllers, may not be able to load device drivers or programs into
the upper memory area. Try adding a DEVICE=SMARTDRV.SYS command before
any DEVICEHIGH commands in your CONFIG.SYS file.
4.2 Intel Expanded-Memory Driver (EMM.SYS)
Use the Intel expanded-memory driver NE or E switch when installing
the driver for Above Board. See your Above Board documentation for
4.3 Phoenix BIOS and HIMEM.SYS
If your system includes a Phoenix BIOS and MS-DOS 5.0 doesn't work
correctly, try adding a /machine:1 or /machine:8 switch to the
DEVICE=HIMEM.SYS command in your CONFIG.SYS file.
