Introduction

If you asked me who is the first to support USB 2.0, I would say that Intel is the first to showcase USB 2.0 support in their range of motherboards. My first encounter with USB 2.0 dated way back in COMDEX 2000, Las Vegas, where Intel first demonstrated an integrated USB 2.0 controller in their new 850 motherboard for the Pentium 4 processor. Showcased at the USB 2.0 pavillion, the controller was connected to various USB 2.0 devices, such as external hard disk drives. What I saw that day was amazing as the USB bandwidth boosted traditional USB 1.1 transfer rates by as much as 40 times.

Since then, Intel has been shipping motherboards with built-in support for USB 2.0. The board's layout was designed for an additional USB 2.0 controller as their I/O Controller Hub 2 (ICH2) did not have built-in support. However, most boards shipped then did not come with the controller, and they were left vacant.

Months passed and we still did not catch sight of USB 2.0. It was only until late last year that peripherals started supporting the new standard. The need for speed was realized when external CD-RW drives needed more than what traditional USB 1.1 could offer. External USB drives could only write at a maximum of about 4x. Anything higher than that would have been risky. External storage also needed the speed as a sustained transfer rate of about 600KB/s would take from minutes to hours to complete huge file transfers. USB 1.1 was simply not feasible to keep up with the needs of today's users.

The Intel D845BGSE is one of the first few boards that came with USB 2.0 support. Utilizing NEC's mPD720100 USB 2.0 host controller, the motherboard could support as many as 5 USB ports - more than enough bandwidth to suit the power user.

Five PCI slots for all the expansion you'll ever need.
