There are actually 3 different PCI card edge connectors types for each BUS width: 1) 5V (only) 2) 3.3V (only) 3) universal (supports either 5V or 3.3V depending on PCI connector type=20 on motherboard) The Supermicro 370DL3/DLE motherboards have two 3.3V 64 bit PCI connectors, but the Tekram DC-390/U3x controllers seem to use a 5V connector. This doesn't fit. This is not due to the SYM53C1010 chip that supports both 3.3V and 5V and thus allows all the 3 types of PCI card connectors (5V, 3.3V and universal). The SYM53C1010-based boards from Symbios/LSI use universal PCI connectors, but they are probably more expensive than Tekram ones. - SYM22915 -> 2 Ultra3 (LVD) SCSI buses - SYM21940 -> 1 Ultra3 (LVD) SCSI bus + 1 UltraWide SCSI bus Thanks to their universal PCI connectors these ones works with both 5V and 3.3V 64 bit PCI connectors on motherboard. =20 G=E9rard. PS1: In my opinion, Tekram choice for the DC-390 U3 PCI board connector couldn't be worse, based on technical considerations. > --David Bushong >=20 > On Sun, Sep 03, 2000 at 06:09:04PM -0400, Brandon D.
