4. Items Evaluated
(1) CD-ROM drive data transfer rate (CD-ROM drive low level test)
Test the data transfer rate for CD-ROM drives under MS-DOS
and MS-Windows
(2) CD-ROM file directory walk test (CD-ROM file system level test)
Test the access speed for CD-ROM file system (MSCDEX) under MS-DOS
(3) CD-Title program execution speed test (CD-ROM application level test 1)
Test the system performance for CD-Titles under MS-Windows
(4) CD-ROM text retrieve speed test (CD-ROM application level test 2)

Test Methodology
================
1. CD-ROM Data Transfer Rate (CD-ROM drive low level test)
Two utilities were utilized:
(1). Microsoft(R) DOSSPEED.EXE: Test CD-ROM speed under MS-DOS
(2). Microsoft(R) WINSPEED.EXE: Test CD-ROM speed under Windows
2. CD-ROM Directory Walk Test (CD-ROM file system level test)
In this test we performed directory walk test (Microsoft BookShelf
CD-ROM) by the batch file:
> TM START (Norton Time Mark)
> DIR E: /S > NUL
> TM STOP
