Using CTRL+F8 to Process Configuration Files on Host Drive (103562)
The information in this article applies to:
• Microsoft MS-DOS operating system 6.2
• Microsoft MS-DOS operating system 6.22
This article was previously published under Q103562
This information applies to both Microsoft DoubleSpace and Microsoft
DriveSpace. For MS-DOS 6.22, use DRVSPACE in place of DBLSPACE for commands
After you press CTRL+F8 to start your system without loading the
DoubleSpace component (DBLSPACE.BIN), you are given the option to process
the configuration files (CONFIG.SYS and AUTOEXEC.BAT) on the host drive (if
there are any).
For example, you can have configuration files on the DoubleSpace-
compressed drive C and configuration files for a different configuration
(such as playing games) on the host drive (such as H).
When you interactively boot your computer without DoubleSpace (CTRL+F8), MS-
DOS interactively processes the configuration files on drive C, which are
normally seen on the host drive H. If you are using CTRL+F8 to simply get
the configuration files processed but you don't want to step through them,
press ESC. (This basically answers yes to all additional yes/no prompts).
NOTE: Any device drivers or terminate-and-stay-resident (TSR) programs
referenced in the configuration files on the host drive must also be
located on the host drive (or an uncompressed drive). For example, if you
have a CONFIG.SYS file on H referencing C:\DOS\HIMEM.SYS, you need to
create a DOS directory on the host drive and copy HIMEM.SYS from C to H.
