: Well, I can't speak for the person who replied to my original note, but
: I have set up sbpcd for my hardware. The initialization time that I was
: refering to occurs after my CD had been detected (which happens very quickly).
: After it detects my CD, it just grinds and gronks away on the drive for
: 25 to 30 seconds before it's statisfied that the drive is ready.

: Not only is that annoying to have happen every time the module
: loads, but it seems rather unnecessary, since the DOS driver for the
: CD initializes it in just 2 to 3 seconds.

Well, I am ready to receive any helpful patches.
But be aware that I am not willing to strip down the delay sequences
and to cut out the status request and reset sequences in general. The
"delivery state" has to be safe for all circumstances.
