Fixed some bugs in cdrom.c;

Browse Source 
Fixed (hopefully) pass through in the Windows CD-ROM IOCtl code;
Fixed the legacy I/O address handling on the BT-958D, now it behaves correctly - legacy I/O address disabled by default, can be enabled in AutoSCSI (removed the setting from the device config struct);
The BT-958D PCI-configured I/O space now correctly gets 32 ports and not 4.
