Hi, William, Thanks. Then how to increase PCI IDE disk speed through adjusting PCI bus speed? What I've said is: even I tried to improve PCI bus speed by specifying "idebus=66", the sustainable PCI IDE disk data transfer speed is still about 33MB/s, while the hard disks themselves may be capable of providing higher speed. Thanks. I definitely know apple and orange, both fruits are my favorite. :) --Guolin Cheng -----Original Message----- From: William Hooper [mailto:whooperhsd3@xxxxxxxxxxxxx] Sent: Friday, April 30, 2004 3:45 PM To: fedora-list@xxxxxxxxxx Subject: RE: disk problems or false alarm??

You are comparing apples to oranges. idebus is the PCI speed in Mhz. 33MB/s is the bandwidth of the PCI bus. -- William Hooper -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: http://www.redhat.com/mailman/listinfo/fedora-list
