- TITLE:
- MS-DOS 5.0 upgrade when STACKER is installed AND boot drive is SSWAPped.
-
- OVERVIEW:
- STACKER has been found highly compatible with MS-DOS 5.0. This bulletin
- outlines the upgrade procedure to 5.0 on a system where the boot drive
- (usually C:) is SSWAPped with a STACKER volume.
-
- ISSUES/COMMENTS:
- 1) If STACKER has not yet been installed, the DOS 5.0 upgrade should be
- performed first, then STACKER should be installed.
-
- 2) If:
- a) STACKER has been installed, AND
- b) the boot drive (usually C:) is NOT being SSWAPped (verify via
- SWAPMAP), AND
- c) there is enough room on C: (2.8 MB) for the MS-DOS 5.0 files, THEN
-
- simply run SETUP from the diskette drive.
-
- It may be necessary to free up room on C: for the MS-DOS files if there is
- not enough room for them.
-
- 3) Otherwise, this procedure assumes that C: is the boot drive, and that it
- is SSWAPped with a STACKER volume. Type SWAPMAP from the \STACKER directory
- to verify. It also assumes that DOS files reside in a directory called
- \DOS. All of the following steps should be taken for a successful upgrade.
-
- RECOMMENDED ACTIONS:
- 1) Boot computer as usual. Change directory to C:\ (root).
-
- 2) Determine names of DOS hidden files:
- Type
- \STACKER\SDIR C:\ /H /P
-
- There are two system files required by DOS; on some systems they are
- MSDOS.SYS and IO.SYS; on others they are IBMBIO.COM and IBMDOS.COM. Record
- which two are listed on the screen.
-
- 3) Install MS-DOS 5.0 to diskettes:
- Regardless of density, an installation from 5.25-inch disks will require
- seven diskettes; if from 3.5-inch disks, installation will require four.
- The diskettes do not need to be formatted. Insert Disk 1 to drive A:. A
- different drive may be used. Type
-
- A:SETUP /F
-
- and follow the instructions on the screen. BE SURE to install MS-DOS 5.0 to
- diskettes that will fit the A: drive for later rebooting.
-
- 4) Prepare to copy system files to STACKER volume:
-
- Reboot from the hard drive.
- Change directory to C:\STACKER. Insert the MS-DOS 5.0 STARTUP diskette to
- A:
-
- 5) Remove attributes on MS-DOS 5.0 system files:
- Type
- SATTRIB -R -S -H A:\IO.SYS
- SATTRIB -R -S -H A:\MSDOS.SYS
-
- (If UNsuccessful, SATTRIB will return a message; otherwise it will simply
- return the DOS prompt.)
-
- 6) Remove attributes on system files in STACKER volume:
- Refer to the DOS system files recorded in step (2).
-
- a) If IO.SYS and MSDOS.SYS, type
-
- SATTRIB -R -S -H C:\IO.SYS
- SATTRIB -R -S -H C:\MSDOS.SYS
-
- b) If IBMBIO.COM and IBMDOS.COM, type
-
- SATTRIB -R -S -H C:\IBMBIO.COM
- SATTRIB -R -S -H C:\IBMDOS.COM
- DEL C:\IBM???.COM
-
- 7) Copy MS-DOS 5.0 system files to STACKER volume:
- Type
- COPY A:\IO.SYS C:\
- COPY A:\MSDOS.SYS C:\
- COPY A:\COMMAND.COM C:\
- COPY A:\COMMAND.COM C:\DOS
-
- 8) Reset attributes on diskette and STACKER volume:
- Type
- SATTRIB +R +S +H A:\IO.SYS
- SATTRIB +R +S +H C:\IO.SYS
- SATTRIB +R +S +H A:\MSDOS.SYS
- SATTRIB +R +S +H C:\MSDOS.SYS
-
- 9) Copy COMMAND.COM to drive which was C: at boot time (SWAPMAP to verify).
- Type
- COPY A:\COMMAND.COM <swapped drive>:\
- COPY A:\COMMAND.COM <swapped drive>:\DOS
-
- Then REBOOT with the MS-DOS 5.0 STARTUP diskette in A:.
-
- 10)Transfer system files to uncompressed (host) drive:
- Insert the MS-DOS 5.0 SUPPORT diskette. From A: type
-
- SYS C:
-
- It may be necessary to re-insert the STARTUP diskette. If successful, a
- "System transferred" message will display.
-
- 11)Remove the diskette and reboot (from the hard disk).
-
- 12)Install MS-DOS 5.0 files to hard drive:
- Move (or delete) existing DOS files from the directory where they reside on
- the compressed drive (usually C:\DOS) then copy in all of the MS-DOS 5.0
- files; this will preserve the paths for CONFIG.SYS and AUTOEXEC.BAT.
- Replace DOS files on the host volume (drive with which C: is SSWAPped
-
- according to SWAPMAP) with the MS-DOS 5.0 versions. Be sure that there is a
- copy of COMMAND.COM in each DOS directory.
