cases, allow the system to continue to boot. See Chapter 4 - System

Q: The computer beeps but I don’t see anything. Why?
A: If your system worked before and you just recently moved your system to a
new location, odds are, something fell off your motherboard or an adapter
card has been worked loose. If this is the case, follow these steps to correct
the problem.
1. Turn off your computer.
2. Open up the case and remove each adapter card one at a time. Re-
seat the card to make sure it makes good contact with the mother-
board.
3. Check to see if the CPU is firmly seated in the CPU socket. It may
have inched out of its socket during the move.
4. Plug the power back in and turn on. If it works - great! If not, read
on.
5. Remove the motherboard from the case and run it on the box the
system board was shipped in or a phone book if you don’t have
the box.
6. If the system boots, the mover probably shorted the board to the
case or the board was knocked loose from the standoffs. Carefully
remount the board into the case and reinstall the controller cards.
Q: What is AGP?
A: AGP (Accelerated Graphics Port) is a new bus architecture for 3D graphics.
The AGP slot eliminates the PCI bandwidth bottleneck by bypassing the
PCI interface and accessing the system memory directly. Currently, the AGP
supports 1X and 2X modes, which yield bandwidths of 264MB/s (at 33MHz
bus speed) and 528MB/s (at 66MHz bus speed), respectively. Compare this
with the mere 132MB/s (at 33MHz bus speed) that you get with the PCI bus.
Q: Does my operating system support AGP?
A: Currently, only Windows 98 and Windows NT 5.0 will have built-in support
for AGP. Some AGP cards require Windows 95 OSR2.1 or a special driver from
Intel. Please check with your graphics vendor for more details.
