I've consulted the archives insofar as possible, but I can't ascertain the status of ASPI support in WINE. Basically, I'm trying to get CD/DVD Speed ( http://www.cdspeed2000.com/ ) to work, because thus far I'm not seeing any Linux tools that will do media testing (C1/C2 error rates and such). I *think* the only relevant entry is: "fixme:aspi:ASPI_ExecScsiCmd Failed" (not terribly informative). From the rest of the error log, it looks like cdspeed.exe is attempting to enumerate devices, and WINE's saying that none of them exist. cdspeed.exe eventually produces the error message "No CD-ROM drives found" and exits. I've got /dev/hdc mapped as a CD-ROM device thru winecfg, and I tried tossing wnaspi32.dll into ../system32 to see if that would improve anything. There doesn't appear to be an ntaspi entry in winecfg to define a redirect for. All thoughts appreciated.
