Abstract: A data transmission sequencing method is disclosed. A data read operation from a primary bus to a secondary bus can be executed without having to wait for the complete transfer of write data stored in posted write buffer transferring to the primary bus, as long as the secondary bus is not in use. In the mean time of the primary bus issues a read operation to the secondary bus, the secondary bus can issues write operation to the bridging device when the secondary bus is not in use. Similarly, there is no need to wait for the completion of read operation. With this type of data transmission sequencing mechanism, idle sessions in a conventional transmission sequencing method are eliminated leading to a higher data transmission rate.

Abstract: A method of adjusting an access sequencing scheme for a number of PCI (Peripheral Component Interconnect) compliant units coupled to a PCI bus system on a computer system. These PCI-compliant units are associated respectively with a set of request signals that allow these PCI-compliant units to request the use of the PCI bus system for data transfer. The access sequencing scheme includes a first-layer access sequence loop and a second-layer access sequence loop, with the first-layer access sequence loop having a higher priority over the second-layer access sequence loop The request signals are assigned to either the first-layer access sequence loop or the second-layer access sequence loop in a predetermined manner. The user can change the assignment of a certian request signal from one loop to the other through PC's BIOS (Basic Input/Output System), so as to allow the associated PCI-compliant unit to have a higher priority level to the use of the PCI bus system.

Abstract: An efficient bearing includes jutting anchor flanges directly extending from a front end of the bearing for coupling with an air fan spindle housed in the bearing. The air fan spindle thus may have a precise axis and less floating or sinking during rotation to achieve better balance. The bearing barrel further has a plurality of plane surfaces formed on the exterior peripheral surface to couple with the air fan seat securely to increase air fan rotation efficiency.
