- It would appear from the haphazard way commands are put into the
- config.sys by install program that the order is irrelevent.
- However, later install programs appear to throw new commands in
- specific positions (such as TCP/IP).
-
- I know of the following constraints in actual loading. Does anyone
- know of a more complete list? (IBM????)
-
- BASEDEV loaded according to extensions
- DEVICE= commands loaded (in order of appearing in config.sys??)
- RUN= commands executed
-
- When do the SET's show up? ie., are all environment variables set
- before any of the DEVICE commands are run or are they added to
- environment in the order they appear and are present for DEVICE
- commands only if they appear before it in the CONFIG.SYS?
-
- When are ifs commands handled? Must be early, but are they order
- sensitive and is before or after BASEDEV commands?
-
- What about quasi-set type commands such as "libpath, protshell,
- buffers, diskcache, codepage, devinfo, ...". Must they be set
- before some DEVICE command runs?
-
- I remember that device=pmdd must go before device=pointdd. Any
- other similar requirements?
-
- How about all the device=\os2\mdos\vxxxx.sys? Again, do their
- corresponding physical drivers have to be loaded first?
-
- I used to understand the operation of CONFIG.SYS and AUTOEXEC.BAT
- for DOS. But I'm completely blind in OS/2 and IBM seems to be moving
- the way of the Mac hiding everything from the user. Is there a way
- to get some detailed technical information? It would make managing
- the systems a lot less trial- and-error if I had the sense I know
- what was going on!
