[ros-kernel] BusLogic 958 SCSI miniport

[Waldo Alvarez Cañizares]

Hi Hartmut:
 
Could you post the test program you used? I can't use it because I do not have SCSI hardisks (only a jazz but I do not have the terminator for the cable) but probably someone wants to give it a try, and could give some hint to know why the results are lower in some cases. I would like to see it.
 
Best Regards
Waldo Alvarez

Here comes the benchmark. My test system is a PII 266 with an intel LX
chip set and two seagate disks.
