Date: Wed, 10 Apr 1996 10:17:26 +0200 Sender: owner-questions@freebsd.org X-Loop: FreeBSD.org Precedence: bulk Hello all. I recently upgraded my 33MHz cpu to a DX2-80, which increased the motherboard/VLB speed to 40MHz. The system is running fine, except for the SCSI stuff. When installing from the SCSI CD-ROM, I get crc-errors during decompression, and reading 16MByte from a unmounted partition on the SCSI disk (/dev/sd0s1 for example) does not always give the same result. Slowing down to a 33MHz external clock seems to avoid the problem, but since the buslogic is supposed to support 40MHz, I'm wondering why it doesn't work. System: SGS-Thomson/Cyrix 486DX2-80 no-name motherboard 16MB RAM Buslogic BT-445S firmware 3.31C (board is rev. B) Fujitsu 1GB disk + Toshiba 3401 CD + archive 2150 tape S3-864 on VLB multi-io on VLB Conner 340MB ide disk soundblaster AWE32 Note that the problem is doesn't seem to be related to freebsd, linux has similar problems (seems to be even worse) Is there someone that knows what may be wrong ?
