This is not formatting a drive.. cg is correct in stating that this is just a parameter that is past to NT when it loads. However, this switch does not allow you to address memory over 3GB.. What it actually does is change the amount of memory that user mode processes can use from 2GB to 3GB.. Here is a snippet that describes what it does in terms of Exchange 2000.. However, you should do this if you are running SQL and some other application because what happens is SQL uses up all of the process memory, and other processes are unable to run.
By default, Windows 2000 Advanced Server reserves 2 GB of virtual address space for the kernel, and allows user mode processes (such as the Exchange 2000 information store process, Store.exe) to use 2 GB of virtual address space. Virtual address space for a specific process is allocated at Startup and increases as more memory is used during run-time. It is normal for the actual memory usage (working set) of a process to be much less than the address space the process was allocated. On an Exchange 2000 server with more than 1 GB of memory, it is necessary to modify Windows 2000 Advanced Server so that 3 GBs are available for user mode applications.

this line in the bootloader merely tells it where win is installed.
multi(0)disk(0)rdisk(0)partition(1)\WINNT="Windows 2000 Advanced Server" /3GB
multi(0) means the primary IDE channel, disk(0) means the first disk, rdisk(0) means the first primary partition, and partition(1) means the second logical disk.
scsi(0) would mean the primary scsi channel
the important thing there would be the /3GB switch, whose implications have been discussed, ie, gives an application more memory than the system overhead associated with the app.
another switch would be /fastdetect which (apparently) makes the OS boot faster.
Hmm...theres something a little peculiar here. Oh i see what it is! the sentence is talking about itself! do you see that? what do you mean? sentences can\'t talk! No, but they REFER to things, and this one refers directly-unambigeously-unmistakably-to the very sentence which it is!
