  Implementing the feature set and efficiency of the VIA Apollo Pro133 chipset, Shuttle Inc. has put together a remarkably powerful microATX form factor system board in their new model Hot-687V. The Hot-687V is a highly integrated IBM PC/ATX compatible system board designed to meet the needs of the industry's most demanding desktop applications.
Equipped with the VIA Apollo Pro133, the Hot-687V is equipped with:
  • A High-Performance 66/100/133MHz CPU interface that supports both PPGA and FC-PGA socket 370 processors
  • An Accelerated Graphics Port, the current high-performance interconnect for graphics-intensive applications, independent of the PCI bus, designed for exclusive use with AGP VGA devices. 
  • A System Memory Controller that supports up to 768MB of standard, PC100 or PC133 SDRAM
  • A Concurrent PCI Bus Controller for the 3-PCI and 1-ISA expansion slots onboard and an integrated Bus Mastering IDE controller featuring two high-performance UDMA33 interfaces which allows up to four IDE devices connection and up to 33 MB/sec of data transfer rates.

   The Hot-687V was shipped to as an engineering sample and so came in a "brown box" with 1 ea. floppy and IDE ribbon cables, a "Quick Start" User's Guide and a drivers CD which included a full online manual as well as the requisite VIA patches and drivers for the Forte Media FM801 onboard sound chip.

   The Hot-687V takes full advantage of the Apollo Pro 133 CPU interface and while the manual only states the system capable of hosting PPGA Intel Celeron CPUs, we had no problem running FC-PGA Pentium III processors at both 100 and 133MHz. The CPU host frequency can be hardwired via jumpers for operation at 66/100 and 133MHz, but also uses VIA phase lock loop circuitry to offer operational frequencies of 75/83/103/112/124/140 and 150MHz. The system board's DRAM controller supports up to 768MB of memory in the Hot-687V's three DIMM slots and by means of asynchronous operation can take advantage of PC100 SDRAM even when using a 66MHz PPGA Celeron through a setting in the BIOS which allows the memory to operate at the CPU host frequency plus 33MHz. This means too, that processors such as Intel's Pentium III 500E, which operates at a front side bus frequency of 100MHz, can be optimized with PC133 SDRAM. The Hot-687's VIA Apollo Pro133 chipset supports 3.3v AGP X2 devices with data transfer rates up to 133 MHz, for data throughput rates of up to 500 MB/sec. 
   Expansion comes in the form of 3 X 32-bit PCI slots and 1 X 16-bit ISA slot, all of which support full-length add-on cards. Considering that Shuttle thought to provide reasonably good onboard sound, in the form of Forte Media's FM801 PCI audio controller chip, expansion seems more than adequate. Forte Media's FM801 is an advanced PCI audio controller and is compatible with Microsoft Windows, DirectX and Adlib Music Synthesizer, Sound Blaster Pro and supports thousands of DOS games.
The on-board I/O controller provides standard PC I/O functions: floppy drive interface, two FIFO serial ports (16550UARTs), an IrDA device port and a SPP/EPP/ECP capable parallel port, PS/2 keyboard and mouse ports and a pair of USB ports.
   The system board hosts a pair of dual-channel PIO mode3/4 UDMA33 IDE channels that support up to four IDE/ATAPI devices and support ACPI (Advanced Configuration and Power Interface) function. ACPI provides
Energy Saving Features for operating systems supporting OS Direct Power Management (OSPM) functionality. Other advanced features include:
