Bang! (1) The 160GB drives are not supportable. Read http://www.48bitlba.com about the 127GB limit for DOS based Windows. A solution might be there but is.. unsupportable.

Bang! (2) Windows 98 (and all DOS based Windows have an issue with over 512MB of RAM. There is a workaround noted by Microsoft (please ask why they didn't fix it?) at http://support.microsoft.com which limits 98's RAM usage to ... 512MB RAM.

Seems to me you overbought here and there?
