Dear all I recently bought a Supermicro P6DLS, a 2PII mobo with an integrated 7880, to which I wanted to connect an IBM Ultrastar 2ES DCAS-34330W. The system is to be used under Linux. I also have a Pioneer CD-Rom connected to the other channel. Unfortunately, the disk behaves pretty slowly. The BootLog for Linux says the reason is that the system does not accept a wide bus, nor synchronous mode. We tried changed cables, setting termination in the BIOS, but to no avail. We also tried the system under Win95 with EzSCSI. EzSCSI says the disk is synch and wide bus, but gives only 3.5 MBps on their benchmark. Has anyone seen similar problems? Any ideas on what is going wrong :-(. Please, also send answers to my personal address (vsc@ncc.up.pt), as I don't subscribe to this list.
