I updated from Win95A to B and I have a TEAC PD-518EK drive installed. It was functioning with Win95A but not after the update. I installed the latest version of PIIX Bus Master IDE Drivers from Intel (Ver 3.02). The drive is recognized by the system but always "not ready". It runs with CD-ROM normally but not with PD medium. TEAC told me, some bus drivers do not support PD. Is there another type of driver required than for hard disks? The TEAC driver is Pdvsd.vxd which is installed but not used by Win95 for the drive.
