Catweasel MK3 and MK4 software update V 0.1.0.7 - fixed recognition problem in Windows XP PRO - on Windows 2000 make sure that update 822831 is installed, otherwise driver might not be recognized - fixed shutdown problem - fixed uninstall problem - added stereo-SID support If you still have an old Catweasel driver installed, you have to remove it manually before installing this one: The driver directory for Win2000 is (drive letter):\WINNT\system32\drivers The driver directlry for Win XP is (drive letter):\windows\system32\drivers Delete the following files: catwea2k.sys [base driver] catdri2k.sys [floppy drive driver] catkey2k.sys [Amiga keyboard driver] catsid2k.sys [SID chip driver] You might not find all of these files in your driver directory, depending on the used options of the cotnroller. Before installing the new driver, make sure to make a hard-reset. Either push the reset button at the right time (experts only), or shut down the computer completely and make a fresh power-up before you start installation. This will ensure proper reset of the MK4 hardware. IMPORTANT NOTICE: Other than mentioned in the manual, Win 9x and Win ME drivers are no longer supported. If you still have one of those old systems, now is the time up upgrade. It's no fun to develop drivers for systems that are not real 32-bit systems. We do like legacy computers, but not legacy stuff that should have been avoided. Our love is devoted to computers with soul! greetings, Achim Dahlhoff and Jens Schönfeld
