Title: CSPPC SCSI setup
Post by: Framiga on December 25, 2004, 05:08:20 PM

Hi all,

some questions about early CSPPC SCSI setup:

i've just installed an UWSCSI hd and i have some strange test results from ScsiBench.

Is this prog reliable?

Could the Syncron option in CSPPC flash, go flushed during the startup? (AOS3.9-BB2+Idefix+OxyPatcher=3reboots)

It is possible to put the Synchron flag, in the RDB?

Cheers

PS- Q-Device, reports that the HD supports Synchron

@Framiga:

You could always check and even set the parameters for the scsi harddrive on the fly, using the UnitControl utility on the Phase5 scsi-disk.

(edit):

I would recommend DiskSpeed (http://de.aminet.net/pub/aminet/disk/moni/DiskSpeed42.lha) for benchmarking your harddrive.

I would go one step further with unitcontrol.
I would use it in the user-startup to set your
drive parameters like you want.  I never had any luck
with the BIOS settings alone.  You can also set
for SNYC operation in the RDB if you like, but the
unitcontrol command line is probably the least painful
to set up.  No worry of accidently screwing up your
RDB.

Hi patrik and billchase

thanks a lot for your suggestions :-)

UnitControl is very useful even if (shame of me), i've just found why ScsiBench gives me weird results . . .

Disabled the CPU Usage idle and now . . .WOW always the same performances :-)

With the Idle enabled, a had sometimes 3-5 MBsec!?!

Thanks again both :-)
