You load a memory manager (emm386 that comes with dos for example) and then
use the DEVICEHIGH in config.sys and LOADHIGH in autoexec.bat to load device
drivers and TSRs high.

Using smartdrv that comes with dos is one way. Type "smartdrv /?" (no
quotes) at the dos prompt for a list of its switches.

Using ramdrive.sys that comes with dos for example you can use system ram to
simulate a disk that can be used as workspace by gcc. ram disks can be
accessed a lot faster than actual disks.

It's an environment variable like BLASTER. Use the SET command to change it.

for example in config.sys:
device=c:\windows\emm386.exe NOEMS NOVCPI

Note that none of the stuff you listed above is REQUIRED. It's a suggested
configuration for optimal performance. I also suggest you read the
msdosdrv.txt in your windows directory.
