- This is anouncing an 'alpha test' of some changes to the scsi system
- I'm looking for guinea pigs.
-
- I have rewritten parts of the scsi tape driver
- it's available in
- ref.tfs.com:/usr/src/sys.extras/julian-scsi/scsi
-
- you'll probably need new copies of the other files in that directory too.
-
- I'd like some brave souls to try it out on fixed record length
- tape drives as I only have the variable type.
-
- main changes are:
-
- better handling of end of file (filemark handling on read)
- better handling of variable record size.
- some minor numbers should push some drives into differnt densities
- hopefilly better handling of some 'silly' drives
- (but this isn't completed yet).. eventually
- this will be run-time configurable with an ioctl interface.
-
-
- Also for the brave..
- sd.c has been changed so that if your drive doesn't support
- the geometry inquiry, it uses a ficticious one.
- Also has a better default disklabel for unlabeled drives.
-
- I only suggest this for people already running my scsi system.
- The rest of the system should remain compatible
-
- hey maybe you want to try the new scsiconf.c too
- (takes a config variable SCSI_DELAY in seconds form the config
- file if you need to wait for a slow device to wake up on boot)
- (also probes faster)
-
- remember
- this is only for experienced scsi hackers or people
- desperate to get a new device working..
-
- Also see the new ultrastore 14f driver support
- First release anywhere!
- Be the second person in the world to run a 14f under 386bsd!
- (real adventurers only) (i386/isa/ultra14f.c)
-
- (if you're an experienced kernel hacker with scsi experience
- who wants a chalenge.. I have a tmc1670 driver 99.5% working..
- apply within..)
