из содержания Microsoft Windows Millennium Edition README for Setup
Код:
If you get any of the following error messages, remove any
memory managers (such as EMM386.exe, QEMM, or 386Max) from
your Config.sys file, and then run Setup again.
Standard Mode: Invalid DPMI return.
Standard Mode: Fault in MS-DOS Extender.
Standard Mode: Bad Fault in MS-DOS Extender.
Standard Mode: Unknown stack in fault dispatcher.
Standard Mode: Stack Overflow.
NOTE: If you still have problems, add EMM386.exe back into
your Config.sys file and exclude all ranges. For example:
device=c:\windows\emm386.exe x=A000-FFFF
If you encounter these messages or if your computer stops
responding during Setup, turn on double-buffering in
SmartDrive. Several SCSI hard drives and some ESDI drives
require double-buffering.
To turn on double buffering, add the following line to
the beginning of your Config.sys file:
device=c:\windows\smartdrv.exe /double_buffer+
where "c:\windows" is the path to your Windows directory.
