Novice questions.

     Hi guys,
     
     I am novice in VSTa, but I have enough background in operating system
     kernel,and device driver programming. I am trying to build driver for
     10/100Mbit DEC21140 chip based Ethernet card. Where I can get
     information about:
     
     1. How small is smallest delay, which I can make by VSTa system calls.
     
     2. How I can get chunk of memory in physical address space more than
     4K. I need it to build descriptors ring and buffer pool.
     
     3. How I can calculate physical address from virtual address.
     
     4. Have anyone information how fast massage passing from kernel
     interrupt routine to driver.
