We have a number of new PII systems (upgraded hardware) IDE drives came out of old P5 system. The drives are currently formatted and running Windows 95C (OSR 2.5). The new systems all came with Windows 98 CDs. It would be really!! nice to use the OEM Windows 98 CDs to upgrade the existing Windows 95 on the IDE drives. We don't relish the idea of starting over clean on all these systems. But, Microsoft's wisdom ;-) says we have to use the Retail upgrade version of 98. Although they will only supply the OEM version with a new system (processor). Has anyone heard of or tested a work around similar to the Windows 95 work arounds for this problem?
