Fedora Core 5 was released yesterday, I attempted to upgrade my existing Fedora Core 4 installation in VMWare Workstation 5.5.0 and encountered a problem.
Fedora isn’t automatically detecting the VMWare SCSI device, it presents a warning that there were no hard drives were detected. I found you can resolve this by manually adding the BusLogic device during setup.
See the following sequence of screenshots.
After doing this everything installed normally, Good Luck!!
