Currently a Trantor driver will support that device (510/770-1400) for all
non-audio related purposes. For audio related purposes you will have to
buy the newly developed FWB CD-ROM ToolKit (which supports most CD-ROMs on
the Mac and follows all of Apple's multimedia specifications, unlike
Trantor) Additionally FWB includes a caching accelerator similar (but much
much baetter) to a CD-ROM accelerator called Speedy CD.

The trantor driver I have (1.33) failed to do some simple audio commands
with a Sony 541 such as:

Stop address method followed by Track hold start point address method
=====================================================
1 MSF Stop - Track Hold MSF - Unpause (FAILED : Did not track and hold)
2 MSF Stop - Track Hold LBA - Unpause (FAILED : Did not track and hold)
3 LBA Stop - Track Hold LBA - Unpause (FAILED : Did not track and hold)
4 LBA Stop - Track Hold MSF - Unpause (FAILED : Did not track and hold)
5 TRK Stop - Track Hold MSF - Unpause (FAILED : Did not track and hold)
6 TRK Stop - Track Hold LBA - Unpause (FAILED : Did not track and hold)
7 LBA Stop - Track Hold TRK - Unpause - Stop LBA (FAILED : Did not track
and hold, and err on Stop)
8 MSF Stop - Track Hold TRK - Unpause - Stop LBA (FAILED : Did not track
and hold, and err on Stop)
9 TRK Stop - Track Hold TRK - Unpause - Stop LBA (FAILED : Did not track
and hold, and err on Stop)
 
 
Stop address method followed by immediate play point address method
=====================================================
1 MSF Stop - Play MSF (worked)
2 MSF Stop - Play LBA (worked)
3 LBA Stop - Play LBA (worked)
4 LBA Stop - Play MSF (worked)
5 TRK Stop - Play MSF (worked)
6 TRK Stop - Play LBA (worked)
7 LBA Stop - Play TRK - Stop LBA (FAILED: Stopped, but returns -36 error)
8 MSF Stop - Play TRK - Stop LBA (FAILED: Stopped, but returns -36 error)
9 TRK Stop - Play TRK - Stop LBA (FAILED: Stopped, but returns -36 error)
 
 
Extra notes: Sony CDU-541 volume changing NOT SUPPORTED with Driver (FWB's
does)
(with LBA multipied by 1!!! and offset by 150)
LBA had to be input differently to match Sony 8001 !!!!!
 

My summary is : The new universal FWB Inc. CD-ROM utilities that are about
to ship supported all 18 of the play commands (and ALL the other commands
besides play commands) and therefore allows the Sony 541 to support all
the required mutimedia commands required by Apple in the CD ROM Developers
handbook 2nd edition. So get the FWB thingie, but if you need it this week
for certain use Trantors driver if audio control is unimportant (or
ProDOS, or caching, or multimedia in general)

PS you could modify the Apple CD ROM driver version 4.0 to replace the
device inquiry string from a CDU "8003" to a Sony CDU "541" with a disk
file Hex editor, I think, because the new driver from Apple should support
the Sony 541 because the new Apple 300i drive (very new) supports all the
Sony 541 commands, and the new Apple driver therefore MIGHT be using the
same commands a Sony 541 uses with its audio and multimedia commands.
