The timing calibration code in the Network Driver Interface Specification (NDIS) driver causes a divide by zero if the CPU runs at 2.2 GHz or faster. This problem does not occur with CPUs that run at 2.1 GHz or slower. Detail solution that you can contact with Microsoft for the following URL.

Windows 95 got the same timing loop problem with P4 platform as occurred on AMD K6/2 processor before. To install Win95 on P4 motherboard, you need to downgrade the processor to 800MHz if possible and load the AMDK6UPD patch file from Microsoft. If the processor frequency is locked like regular retail processors, Win95 and the AMDK6UPD patch have to be preloaded on another platform to get rid of the IOS protection error. The AMDK6UPD patch is available from the following URL.

M7TDX series motherboard use Intel 845 Chipset as MCH (Memory Controller Hub). Based on Intel 845 Chipset specification, 845 Chipset only able to support AGP 4X mode. The main different between AGP 1X, 2X, and 4X is the VGA operating voltage. AGP 4X Is using 1.5V and AGP2X/1X are using 3.3V. The 845 chipset will be damaged If AGP2X VGA card Is used. Biostar have added a protection circuit to prevent the MCH to be burned out when installing an AGP .

M7TDR is using the same Chipset(Intel 845) as M7TDB uses. This Chipset support both socket 423 & Socket 478 CPU. These two type of CPU are basiclly the same, both of they utilized the 0.18-micro process technology. However the M7TDR Is using Socket 423 CPU and the M7TDB using Socket478 CPU.

Yes, you can use the new Intel Celeron Socket 478 pins CPU on M7TDF.

Intel has integrated the USB 2.0 version on ICH4, but USB v2.0 driver Is provided by Microsoft instead of Intel. Microsoft has intergated the USB v2.0 driver into their operating system such as Windows XP/2000. Please refer to your Windows XP installation CD or link to Microsoft WebSite to download the latest driver for USB 2.0. However, Microsoft will not provide USB v2.0 driver On Windows NT/98/98SE/ME or early version.

No. Base on the Intel 845G Chipset Specification; it can only support DDR 200/266 Unbuffered, non-ECC DDR SDRAM Memory.

Yes. The Motherboard P4TGT using the Intel 845GE ChipSet. This Chipset feature, contain an integrated video core known as Intel Extreme Graphics, support 266MHz graphics bus and up to 64MB of Dynamic Shared memory.

Motherboard model M7TDB use Intel 845 Chipset.According to Intel 845 Chipset specification, It only supports AGP 4X graphic card with 1.5V operating voltage. That mean, Intel 845 chipset's motherboard will not support AGP 2X graphic cards which Is required 3.3V as operating voltage.

That is the LAN function which is inculded under Intel South Bridge (ICH2) Chipset. With Real-Tek LAN chip on board, you don't have to add a PCI LAN card and you can use the intro-net function with M7TDA.
