I have the same problem with the cd-rom version. The devices don't change. It always reads sis0 and sis1. I tried latest stable and beta release. Tested on PII with RTL8139 cards and VMWare. I don't use a floppy drive and want to inject config later by web gui if possible. I also installed the cd-rom version to hdd (on vmware) but it doesn't change anything. Maybe there's something hardcoded to use the floppy and it doesn't work without.
Any solution known?
You must have something to store the config, a floppy or USB flash drive. Read the quick start guide.
