Message SU0011:
If your hard disk is password–protected, Setup will not complete
successfully. You must first remove the password protection. For
more information, see the documentation for your computer.

Standard Mode Messages:
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:windowsemm386.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:windowssmartdrv.exe /double_buffer+

where "c:windows" is the path to your Windows directory.

Setup Could Not Back Up Your System Files message:
If you see this error message while Setup is saving your system
files, you may not have enough disk space, particularly on
compressed disks. Free up space on the drive that you are saving
your system files on (the default drive is C) by removing unneeded
files.

Uninstall can require up to 110 MB on many systems. If Setup is not
offering you the choice of saving your system files, you may be very
low on free disk space.

Cannot Continue on This System Configuration:
If you get this message, you may have an older, incompatible disk
partition. Before you run Setup, you must back–up your data and
then repartition your disk.

Sorry, ale nie chce mi sie wglebiac w ten problem.
