I'd like to read Mode 2 Form 2 sectors from a CDROM under FreeBSD. Any ideas on how I might do this? What are Mode 2 Form 2 sectors you ask? On the regular ole CDROM, sectors are made of 2048 data bytes and around 233 bytes of EEC data. Mode 2 Form 2 sectors don't have an EEC section. The entire 2048+233 bytes form a single 2263 or so byte sector. These Mode 2 Form 2 sectors can be read via MSDOS'es mscdex READLONG call on CDROM drives which are capable of reading Mode 2 Form 2 sectors. What I am looking for is some direction on how I might go about reading these Mode 2 Form 2 sectors via the FreeBSD SCSI device drivers. Thanks, Brian Litzinger brian@easynet.com
