HD Install :: can't find KNOPPIX filesystem

For slow USB devices, don't forget we also have the waitusb boot option.

A significant difference between 3.x and 4.x has to do with SATA drive support. 3.x has no such support. 4.x has limited support only by using the sata boot option. Because sata modules had to be included in minirt some old SCSI modules were removed. If 3.x booted and 4.x does not then perhaps an older scsi module was required.
