Time for some more detail. The 895 is capable of Ultra2 transfers. To do this it has a 4x clock multiplier, not a 2x clock multiplier. Your settings pretend the 895 only has a 2x multiplier. If you use these settings, then when sending data to the disk, it will be sent 2x faster the disk expects. This may be OK, because disks are often over specified, but it is risky for a fileserver. If you wait a short time, I will post a modified version of scsincr53c8xx.c which is better for you. Not perfect, but better. --upas-ptxjmxypxxtrnqymvxewhmnqqj Content-Type: message/rfc822 Content-Disposition: inline Received: from tele-punt-22.mail.demon.net ([194.217.242.7]) by cpu; Fri Jul 28 11:22:53 BST 2000 Received: from punt-2.mail.demon.net by mailstore for ngr@cotswold.demon.co.uk id 964779021:20:12174:125; Fri, 28 Jul 2000 10:10:21 GMT Received: from hearno.cyberware.co.uk ([194.74.221.2]) by punt-2.mail.demon.net id aa2028138; 28 Jul 2000 10:09 GMT Received: from cse.psu.edu (majordom@claven.cse.psu.edu [130.203.3.50]) by hearno.cyberware.co.uk (8.9.1b+Sun/8.7.2) with ESMTP id LAA03054 for ; Fri, 28 Jul 2000 11:08:02 +0100 (BST) Received: from localhost (majordom@localhost) by cse.psu.edu (8.8.8/8.8.8) with SMTP id GAA12364; Fri, 28 Jul 2000 06:08:25 -0400 (EDT) Received: by claven.cse.psu.edu (bulk_mailer v1.5); Fri, 28 Jul 2000 06:08:18 -0400 Received: (from majordom@localhost) by cse.psu.edu (8.8.8/8.8.8) id GAA12341 for 9fans-outgoing; Fri, 28 Jul 2000 06:08:13 -0400 (EDT) X-Authentication-Warning: claven.cse.psu.edu: majordom set sender to owner-9fans using -f Received: from ar.aichi-u.ac.jp (none@ar.aichi-u.ac.jp [202.250.160.40]) by cse.psu.edu (8.8.8/8.8.8) with SMTP id GAA12337 for <9fans@cse.psu.edu>; Fri, 28 Jul 2000 06:08:07 -0400 (EDT) Date: Fri, 28 Jul 2000 06:08:07 -0400 (EDT) From: arisawa@ar.aichi-u.ac.jp Message-Id: <200007281008.GAA12337@cse.psu.edu> To: 9fans@cse.psu.edu Subject: Re: [9fans] 53c895 failed to INIT MIME-Version: 1.0 Content-Type: text/plain; charset="US-ASCII" Content-Transfer-Encoding: 7bit Sender: owner-9fans@cse.psu.edu Reply-To: 9fans@cse.psu.edu Precedence: bulk Hello, We can find the line: #define SYM_895_DID 0x000c in scsincr53c8xx.c. However it seems this is not used anywhere. We can also find following lines bellow the line. { SYM_875_DID, 0x01, "SYM53C875r1", Burst128, 16, Prefetch|LocalRAM|BigFifo|Differential|Wide|Ultra }, { SYM_875_DID, 0xff, "SYM53C875", Burst128, 16, Prefetch|LocalRAM|BigFifo|Differential|Wide|Ultra|ClockDouble }, { SYM_885_DID, 0xff, "SYM53C885", Burst128, 16, Prefetch|LocalRAM|BigFifo|Wide|Ultra|ClockDouble }, { SYM_896_DID, 0xff, "SYM53C896", Burst128, 16, Prefetch|LocalRAM|BigFifo|Wide|Ultra|ClockDouble }, SYS53C895 does not apear here. Therefore init fails. Does it mean SYS53C895 is not supported? I added entry: { SYM_895_DID, 0xff, "SYM53C895", Burst128, 16, Prefetch|LocalRAM|BigFifo|Wide|Ultra|ClockDouble }, and ran 9pcfs (based on emelie), then I reached "config:" message without error message. now I am formatting.... I will report the result. Kenji Arisawa E-mail: arisawa@aichi-u.ac.jp --upas-ptxjmxypxxtrnqymvxewhmnqqj--
