I use tools RW t0 check PCI register offset:A0h bit 0 and 1 are "00" [ Disable ]

I want setting to 01 (Enable)

but I can not change this bit by RW. Does XIO3130 have any protected bit need to be modified?

Hello Kerr,

Sorry for the delay, we were able to reply this behavior at our end, the value is changed again because the Windows driver is forcing the default value even when the register is RW capable, unfortunately as this is the native Windows's driver we cant manage this driver.

Regards,
Roberto

Hi Roberto

I have try win7 with system for TI X3130

1.For System Power Policy setting balanced mode

Picture of DSCN6911~DSCN6914

2.For System Power Policy setting Power Saver

Picture of DSCN6915~DSCN6918

I don’t know which bus (bus have 2~3 , device have 00~02) for TI , so take many picture to check.

If only check bus2 device00 the value also 41H . (we want to modify to 40H disable ASPM for try)

or This seeting by windower driver , so we can not setting this bit (A0H)?https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/138/Pic.7z
