For GX2 + GX5535 CHIP
A.
***** CPU Speed = (PCI*FbDiv)/VDiv *****
Note :
FbDiv (Reg 4C000014,Bit32 ~ 37) must use transfore table to get value.
VDiv (Reg 4C000014,Bit38 ~ 40) must add 2
exsample:
REG , EDX , EAX
1. 4C000014h = 00000210h, 06DE0158h
PCI freq. = 66MHz, FbDiv = 16 , VDiv = 0
2. FbDiv (GX Processors Data Book Table 6-64) use transfore table
to get PLL Divider Results = 12
3. CPU Speed = (PCI*FbDiv)/VDiv
= (66*12)/(0+2)
= 396 MHz
=============================================================================
B.
***** Memory Speed = GeodeLink Speed = (PCI*FbDiv)/MDiv ***** use transfore table
Note :
FbDiv (Reg 4C000014,Bit32 ~ 37) must use transfore table to get value.
MDiv (Reg 4C000014,Bit41 ~ 44) must add 2
exsample:
REG , EDX , EAX
1. 4C000014h = 00000210h, 06DE0158h
PCI freq. = 66MHz, FbDiv = 16 , MDiv = 1
2. FbDiv (GX Processors Data Book Table 6-64) use transfore table
to get PLL Divider Results = 12
3. Memory Speed = (PCI*FbDiv)/VDiv
= (66*12)/(1+2)
= 264 MHz

About WinNT 4.0 support:
AMD Geode GX2 + CS5535 no support WinNT 4.0. Because NT4.0 does not recognize
the CPU ID. This is information from AMD Geode.(2005/01/12)
=============================================================================
005.
About USB Status:
1.It does not support boot for USB CD Rom now.
2.When useing USB device boot,the BIOS hang on 4Xh or 81h.
The 4Xh debug code that mean VSA does no response.
The 81h debug code that mean VSA finish but USB device have stall status.
=============================================================================
006.
About IRQ Status:
If audio and USB share the same IRQ , the device will have some problem.
=============================================================================
007.
About PCI S3 VGA card Status:
The sysyem hanged when use PCI S3 VGA card. You must set reg 32h/FFh and reg 33h/E7h.
Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
