Introduction:

 Welcome to ALi(Acer Labs Inc.) AGP Control Center. ALi developed this program to facilitate end users` both setting up AGP driver configuration and optimizing 3D-graphics rendering performance according to users` requirements.

ALi AGP Control Center


ALi AGP Control Center:

To use ALi AGP Control Center, you must install Ali AGP driver V1.64 or above version. The first figure shows five selectable buttons which provide users quick option to manage graphic performance and stability, including ..

Status: Show AGP status.

Normal: Set default value.

Safe: Set to be a robust mode when meet some graphics problem.

Turbo: Set high speed.

Manual: Set detail configuration, should be operated by specialist or engineer.

Log Register to File: Read PCI configurations and save to files of

C:\ALIB0D0.log, ALIB0D1.log and ALIVGA.log


Status Mode:

If status button is pushed, it will show the current settings of AGP status.

Vendor:

North-bridge manufacturer.

Device ID:

North bridge device number including 1541/1621 etc.

Base Address:

North bridge`s PCI-configuration address.

AGP Enable:

Enable AGP function or not.

Side Band:

Enable Side Band or not.

GAT Mode:

Flush buffers before granting the bus ownership.

0: Conditionally concurrency between CPU and PCI bus.

1: No concurrency between CPU and PCI bus.

2: Fully concurrency between CPU and PCI bus.

AGP Rate:

Supported AGP speeds, includes default , 1X, or 2X . AGP speed is 0 when default radio button is selected else is 1X or 2X.

Fast Write:

The type of access is to pass data/control directly to the AGP master instead of placing the data main memory and then having the AGP master read the data.

Queue Depth:

AGP request queue depth.

Frame Buffer Size:

Size of frame buffer disable, 1M, 2M, 4M,8M, 16M, or ALL.


Normal Mode:

It shows the default driver setting. Push the button, the driver setting will be restored to the original setting. It avoids the user making unrecoverable error.


Safe Mode:

In Safe Mode, it keeps AGP card running robustly but slowly. In general, Safe Mode is chosen when system crashed at playing/installing 3D game or booting to windows 95/98 when set in Normal Mode or Turbo Mode. If system can not boot into windows safe Mode first, execute this tool to set in the Safe mode, and reboot.

If the safe mode still can`t conquer the above error, then please select Manual Mode and select PCI mode, select apply and exit to reboot.


Turbo Mode:

It adjusts the performance in the highest degree.


Manual Mode:

Note that If you are not a specialist or familiar with AGP, do not try this mode. Some options have been proved to improve graphics rendering performance, however, when some options are set will halt the system. If system halted, to set in the Normal Modeto reset to default value is necessary. See the Manual options for detail introduction.


Manual Options:

AGP data rate :

Adjust AGP-device speed .

Force Side Band Disable:

Disable Side Band.

PCI Mode:

Run in PCI-BUS speed.

PCI Retry Counter:

Enable this function, North bridge will retry 0xff  times to send command. This function is for M1621.

Set K6 EWBEC:

Set K6-2/3 Extended Feature Enable Register (EFER) EWBE Control to tune K6-2/K6-3 performance.

Use UC For WC:

Use the Uncacheable memory as write-combining memory.

GTLB always Fetch:

Force always prefetch GART Table.

Reset AGP command:

Only for reset ATI AGP command register for resume from suspend.

AGP Timing:

Disable concurrently access bus.

Frame Buffer Size:

Size of frame buffer is disable, 1M, 2M, 4M, 8M, 16M, or All.

Fast Write Function:

    Default: use default settings.

    Enable: enable Fast Write function.

    Disable: disable Fast Write function.

AGP delay Clock:

This control the status of digital PLL for 1541 internal AGP clock source. Note: To adjust this field may halt the system, however, to tune slightly is preferable.

SDRAM Delay Clock:

SDRAM DPLL counter. Note: To adjust this field may halt the system, however, to tune slightly is preferable.

Disable PCI read Prefetch:

Disable prefetching PCI read data.

Force Alert Request:

Favor CPU to access PCI.

Write Allocation:

Default: Bypass the setting. BIOS, or drivers determine the value.

Disable: Disable write-allocation function.

Enable with hole: The memory hole (between 15 Mbytes to 16 Mbytes) is provided for a small number of uncommon memory-mapped I/O adapters that use this particular memory address space. This item is suggested to be selected after the next item (Enable without hole) is tried.

Enable without hole: Enable write-allocation function and use memory area between 15 Mbytes to 16 Mbytes.

PAD Input Level Selection: Adjust PAD Input Level Selection.


Log Register to file:

Log PCI configurations of north bridge and VGA card to files of C:\ALIB0D0.log, ALIB0D1.log and ALIVGA.log. If you need technical support, please fill description form to describe your system configuration, copy contents of those files and past to Description dialog of cologic form
