what the heck is ramdrive.sys

I am working on a friend's computer.  The config.sys is calling for "device high=C:\windows\ramdrive.sys /E 2048.
I noticed that, until I rem'd this command out, there was a Ramdrive on the system.  But what does it do and why is it needed?

RDaves, please also see your other questions as well as my comments.

Normally, when you use the Windows 98 Startup Boot disk to boot the system in anticipation of either doing a repair or a fresh install of Windows 98, the boot disk will create a ramdrive in memory and will copy various disk tools to it, such as fdisk, format etc.

This is by design and enables you to access these tools without using the floppy after the boot has occurred. The config.sys file from this floppy was not designed to be copied to the hard drive, which is why the error. ramdrive.sys is on the Win98 Startup Boot Disk.

Dew Associates, Dennis
First, thank you for all you help.  It is much appreciated.
Second:  I still do not understand the function of Ramdrive.sys.  I have rem'd this out of my Config.sys and there seems to be no difference in how my machine runs.  It would seem that if this ramdrive thing was necessary, that certain programs would be looking for it and I would get some kind of message that something is missing.  Additionally, I have no Idea how to use this feature myself.  In your explanation, you say: "Normally, when you use the Windows 98 Startup Boot disk to boot the system in anticipation of either doing a repair or a fresh install of Windows 98, the boot disk will create a ramdrive in memory and will copy various disk tools to it, such as fdisk, format etc". Okay, this I understand.  It is necessary for the ramdrive thing in the above situation, but then what?  What good is it?

Okay, I understand your confused and here's why.

Normally when using the Win98 startup disk to load windows 98, you wouldn't copy the autoexec.bat or the config.sys to your hard drive in order to continue. In your case you did this without also copying the other files that are called in either of these files.

As an example, the line, "device high=C:\windows\ramdrive.sys /E 2048" is called in the bootdisk config.sys, but would never be needed on your actual PC. This is used exclusively by the boot disk. You copied the config.sys to your hard drive thinking that you needed it, when in reality, you didn't need it at all.
