- MBOOT
-
-
- Douglas Boling February 26, 1991 (Utilities)
-
- Purpose: Permits selection at boot-up of up to four configurations
- (sessions), each of which may use a different CONFIG.SYS, AUTOEXEC.BAT, and
- version of DOS; one session may use OS/2. Provides adjustable timeout for
- default session and menu-driven installation and selection procedure.
-
- Format: MBOOT d:
-
- Remarks: MBOOT must be installed on a boot drive or diskette, so d: is
- normally limited to C: or A:. The various sessions are initially set up
- through a conventionally-controlled menu system before MBOOT itself is
- finally installed with the Install menu option. MBOOT replaces the normal
- DOS boot record on the disk and gains control so that it can rename and write
- the needed DOS system files in their required locations. MBOOT also renames
- the various user-prepared CONFIG.x and AUTOEXEC.x files, all of which must be
- stored in the root directory, to CONFIG.SYS and AUTOEXEC.BAT, as appropriate
- for the specified session.
-
- The largest (latest) version of DOS to be used should be installed
- on the PC before installing MBOOT. Subsequent DOS versions may then be
- addedfrom MBOOT's Load Operating System Menu. Other version-specific DOS
- command files, including COMMAND.COM, must be kept in separate directories
- for each DOS version. The user-prepared CONFIG.x and AUTOEXEC.x files must
- each contain a line to specify this directory. Thus, assuming a a boot drive
- C: with a \dos32 version directory, the root directory CONFIG.32 file should
- contain the line
-
- shell=c:\dos32\command.com /p
-
- and the root directory AUTOEXEC.32 file should contain
-
- set comspec=c:\dos32\command.com
-
- If OS/2 is to be used for one of the sessions, it must be
- installed with its own procedure and with its dual-boot option. MBOOT is then
- installed from DOS and not from the OS/2 DOS Compatibility Box. Note that
- MBOOT cannot be installed on a machine using the new OS/2 HPFS (high
- performance file system) format.
-
- Note: Back up your hard disk before installing MBOOT. While it has been
- successfully tested on variety of machines, this precaution should be taken
- with any program, such as MBOOT, that writes to the boot-up clusters of the
- disk.
