TECHNICAL SUPPORT BULLETIN FILENAME: TECH014.DOC NUMBER: 014 SUBJECT: DOS5.0 DATE: June 18, 1991 TIME: 5:11 PM SOURCE: Tech Support RELEASE STATUS: Public 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.
