[comp.sys.mac.programmer] SCSI delay before trying to boot

louis@asterix.drev.dnd.ca (Louis Demers) (02/12/90)

I would like to know how to adjust the delay that the mac waits
before trying to boot off a SCSI disk.

I heard there is a value in PRAM  to that end.  I would like to
lenghten such a value because one of my drives takes a long time to
spin up and I always end up booting on the others.  Anybody has
any info on the subject or better yet, a cdev that would allow
me to adjust it.

While trying to figure out where were stored the menu delays,
(see thread on Hierarchical Menus) I fould values in PRAM that
were used by the SCSI manager, but before risking to play with
those, I would like to know id anybody has info on the topic.

See GetTimeOut and SetTimeout in Inside Mac volume 5 (p. 349+).
