Installing russian Windows 98 (or other) on a computer with latin char Windows

[Sergej Balon]

When I try to install additionally a russion version of Win98 on a computer on which currently a windows98
with latin chars exists - is this possible ?

Assume the worst case: NOT - I tried to install the russian version by overwriting/removing the current
installation during the install process. For that I booted with english DOS boot floppys
and tried to call the setup.exe from the original russian Win98 cd.

The call itself was successful but the after some seconds a dialog pops up informing me about something.
The problem is that I cannot read the popup information because the cyrill chars are interpreted by
latin chars.

How can I cope with this problem ?
What do I need for installing a russian Windows98?
Do I really need russian DOS boot floppies?

Thanx
