In addition, advanced features are supported such assnoop ahead,snoop filtering, L1 write-back forward to PCI master, and L1 write-back mergedwith PCI post write buffers to minimize PCI master read latency and DRAM utilization. Delay transaction and readcaching mechanisms are also implemented for further improvement of overall system performance.
The VT8235CD“V-Link Client Controller”is a highly integrated PCI /LPC controller. Its internal bus structure isbased on a 66 MHz PCI bus that provides2x bandwidth compared topreviousgeneration PCI bridge chips. The VT8235CD also provides a 533 MB/sec bandwidth Host / Client V-Link interface with V-Link-PCI and V-Link-LPC controllers. It supportssix PCI slots of arbitration and decoding for all integrated functions and LPC bus.

Each time the computer is turned on, the system BIOS runs a series of internal checks on the hardware. This power-on self test (post) allows the computer to detect problems as early as the power-on stage. Error messages of post can alert you to the problems of your computer.If an error is detected during these tests,you will see anerror messagedisplayed on the screen. If the error occursbefore the display is initialized, then the screen cannot display the error message. Error codes or system beeps are used to identify a posterror that occurs when the screen is not available.
The value for the diagnostic port is written at the beginning of the test. Therefore, if the test failed, the user can

determine where the problem occurred by reading the last value written tothe port bythe debug cardplug at MINIPCI slot.

7.2 Diagnostic Tool for Mini PCI Slot
The Mini PCI DOG killer card is a single-stepdebug tool whichutilizes Mini PCI interface (Type III A) and is ableto hold a PCI bus cycle so that address, data and control bus states on PCI bus can be inspected. Especially, the tool can help an engineer trace address/data bus for BIOS read cyclesas soon as power on and debug open or short circuit problems easily. Usually, thissort of problem will make a PC motherboard fail to boot.
