what are processor to i/o controller and lpc controller interface?

Do you want general information or information specific to your
system?

If things like Google searches don't help with answers, we can look up
your hardware information for you after you:

Click Start, Run and in the box enter:

msinfo32

Click OK, and when the System Summary info appears, click Edit, Select
All, Copy and then paste

There will be some personal information (like System Name and User
Name), and whatever appears to
be private information to you, just delete from the pasted
information.

This will minimize back and forth Q&A and eliminate guesswork and
assumptions.

LPC = Low Pin Count bus from Southbridge to SuperI/O chip.

http://en.wikipedia.org/wiki/Low_Pin_Count

"Intel 82845 Processor to I/O Controller - 1A30"

Processor
|
| Front Side Bus (FSB)
|
82845
Video -- AGP ---- Northbridge --- SDRAM DIMM slots
|\
| \___ 1A30 is right there
|
|
| Hub Interface Bus
| 66MHz clock, 266 MB/sec data
|
82801BA
Southbridge
USB -------- "I/O Controller Hub" -------- PCI bus
(ICH2)
|
| LPC bus
|
SuperI/O
Chip for low speed input/output
| | |
Parallel Floppy Serial
Port Port

Look for references to "1A30" in here. See PDF page 43.
