Bios setting questions for nForce 570 MB

[videobruce]

I have a Foxconn N570SM2AA MB w/ a nForce570SLI chipset.
I haven't kepted up with all the changes in the past 3 or so years and there are plenty of 'new' settings in the Award bios I need an explanation of. Of course the manual is somewhat useless (that hasn't changed over the years).

Ok, what do all of these mean;
1. LDT Voltage Select,
2. PMU function
3. K8<->SB HT Speed (bandspeed of the links xmitter),
4. K8<->MCP55 HT Width (bandwidth of the links xmitter),
5. Onboard Super IO,
6. AC Media Interface,
7. Reset Config Data (whether the system automatically distributes DMA & I/) addresses each time the PC is turned on)
8. Maxium Payload size (max. TLP payload size for PCI-E).

Text in () were taken from the manual. Thanks in advance.

hi bruce,

1. LDT Voltage Select
3. K8<->SB HT Speed
4. K8<->MCP55 HT Width

other CPUs has a FSB, the A64 (K8) has a HT-Link, others call it LDT (default: 1000MHz, 16bit up/16bit down)
a good bios contains the following options:
- reference clock htt (default: 200MHz)
- LDT multiplier (default: 5x)
- LDT bandwidth (default: 16/16)
so 5x200MHz=1000MHz

6. AC Media Interface

sounds like a realtek audiochip

2. PMU function
5. Onboard Super IO
7. Reset Config Data
8. Maxium Payload size

no idea

Ok, there is a (what I call) a 2nd page that shows the additional IDE controller (nForce5 only has a single controller within the chipset) and the single Optical drive attached. There is also a "Press any key to continue" message with a five (?) second countdown (slowing the boot process up).
Can that be changed?

It has two SATA chip controllers.

But, I'm not using either and they are disabled. That screen is for thew 2nd IDE controler
