What kind of drive is a Maxtor 7850 AV? If it's some kind of IDE drive
then I don't think you'll need a special driver.

The ATAPI driver goes in CONFIG.SYS. The MSCDEX driver goes in
AUTOEXEC.BAT.

Syntax is a bit tricky. The ATAPI driver typically needs a name
specification, which you then also put on the MSCDEX line so MSCDEX can
find the ATAPI driver. The MSCDEX syntax for this name is "/D:MSCD000"
if, for example, your ATAPI driver has the name MSCD000.

The CD-ROM's drive letter is specified by MSCDEX's /L parameter (for
example, "/L:R" if you want the CD-ROM to be drive R). If you don't use
/L then the first available drive letter after your last hard drive is
used. Note that you can get into a RAM drive conflict, so if you're
using a RAM drive then you should use /L to specify a drive letter.

MSCDEX has a number of other command-line parameters. /E uses expanded
memory for the sector buffers. /V is verbose mode (so you can see what
it's doing when it loads). /M specifies the number of sector buffers.
There are others but you probably don't need them.

Load them "high" if you want more DOS memory for your programs and
TSR's.
