Two things I would look at:
Win2k spends a good amount of time querying hardware before boot. For instance, it will scan all your IDE controller Channels (Primary and Secondary). If you're not using all of these channels, setting them to "None" in Device manager vs. "Auto Detection" will tell Win2K not to even look at that channel and go to the next.
So, for example, if you have one hard drive on Primary IDE Channel Device 0 position and no device on Primary IDE Controller
Channel Device 1 position, set Device 1 position to None vs Auto Detection. If you're not sure what I'm talking about, right-click on your My Computer icon on your desktop and choose Properties. Then, click the Hardware Tab, then, click the Device Manager tab. You should see a listing for "IDE ATA/ATAPI controllers" Click on that to open it. Now, you should see three entries. The second and third are labled as Primary IDE Channel and Secondary IDE Channel. Click on Primary. Then, click on Advanced Settings. You'll see "Advanced Settings". You'll see "Device 0" and "Device 1". If you have no second hard drive or cdrom on the Primary IDE controller, set device "1" "Device Type" to "None". If you're using both the Device 0 and Device 1 positions on that controller channel, leave them at Auto Detect. Just make sure both are set to "DMA if Available".
Do the same for the secondary channel. If there's a position there that's not being used, set it to "None". Make sure both are set to "DMA if Available".
Just make a note to yourself, though, that if you ever install an IDE device on one of your motherboard controllers that you've set to "none" in Win2k, you'll never see it detect until you go back and reset it to Auto Detection.
Now, that's one thing to speed up the boot. Another is to stop any unneeded "Services" from running at startup. Here's a good website (there are a few) that walks you through the process of disabling services you would never use:
