[comp.sys.att] AT&T MSDOS 3.21

josephs@ttidca.TTI.COM (Bill Josephs) (02/03/88)

I just got my MDOS 3.2 from AT&T (after calling five 800 numbers to
get the correct COM code number... )-:  ).   Does anyone have any
effective guidelines for using the AT&T supplied Disk Cache?  How does
it work?  Is there any way to temporarily desable for disk surface
analysis programs or must one reboot with a different config.sys.

The details on using the cache are in the HELP feature that is
distributed with AT&T MS-DOS 3.2 Rel 2.02. It should also be in the
manual.
However here is what you have to do.
in the config.sys file do:
device=[drive:][path]ac.sys [bbbb] [/E] [/Rn] [/A]
where
bbbb = amount of memory in multiples of 1K i.e., 1024 for a 1M cache.
/E if using extended memory (286 and 386 computers only)
/A if using expanded memory (with Memory Manager loaded first)
DON'T USE BOTH OPTIONS AT ONE TIME.
without the / option it will load a cache in conventional (under 640K)
memory.
/R Read specified number of disk sectors. ( 2, 4 , or 8) default is 4.

NOTE: with the exception of using the memory manager and the /A option
with AC.SYS, AC.SYS MUST be loaded first in the config.sys file.
