Created Driver Disk from Beta2 images/drivers.img using dd. At the stage of the install where the Driver disk is requested the following is output to VC4: <4>VFS: Can't find a valid MSDOS filesystem on dev 02:00. This results in the list of available drivers being displayed empty.
This is a normal message, the driver disk can be either dos or ext2. When you take bootnet.img on a system where the network card is not detected for example, and then press F2, insert the driverdisk and press enter, the driver disk is recognised and the list of networkdrivers does become larger. Trying to use a driver from the disk fails one step later btw, but the disk is recognised, the failure is an other bug which is already in bugzilla. I guess your talking about trying todo an install form a propietary interface cdrom, that is an unrelated bug in the driver disk itself which is also already in bugzilla.
