The SCSI data buffer is now zeroed before being allocated, MODE SELECT data is therefore no longer lost in transit;

Browse Source 
SCSI DMA writes (for MODE SELECT) now correctly use InitLength instead of request_length when bus type is SCSI;
Fixed MODE SELECT page saving;
CD Audio volume is now correctly initialized on card initialization for all Sound Blaster variants, fixes CD Audio being muted when booting without the Sound Blaster initialization program;
Brought the Sound Blaster variants back to a sane sound volume but still louder than the old quietness;
Moved SCSI adapter initialization to before sound card initialization, fixes DOS SCSI CD-ROM driver hangs under some conditions.
