- * Options :
- * AUTOSENSE - if defined, REQUEST SENSE will be performed automatically
- * for commands that return with a CHECK CONDITION status.
- *
- * PSEUDO_DMA - enables PSEUDO-DMA hardware, should give a 3-4X performance
- * increase compared to polled I/O.
- *
- * PARITY - enable parity checking. Not supported.
- *
- * SCSI2 - enable support for SCSI-II tagged queueing. Untested.
- *
- *
- * UNSAFE - leave interrupts enabled during pseudo-DMA transfers. You
- * only really want to use this if you're having a problem with
- * dropped characters during high speed communications, and even
- * then, you're going to be better off twiddling with transfersize.
- *
- * USLEEP - enable support for devices that don't disconnect. Untested.
- *
* The card is detected and initialized in one of several ways :
* 1. Autoprobe (default) - since the board is memory mapped,
* a BIOS signature is scanned for to locate the registers.
