i want to create an image drive on floppy msdos-startup disk using
device=ramdrive.sys 4096 /e , on config.sys
..i want to ask:
1. to successfully create it, do i need ramdrive.sys file on my windows folder?
   (i didn't find it, how to create it ??)
2. as i know the syntax..
device=[drive:][path]RamDrive.sys  [DiskSizeSectorSize NumEntries] [/e][/a]
, using drive and path for what??? it's on floppy right?
3. what is the diffrent between extended and expanded memory..?
sorry.. if too many questions.. i hope someone could help me..1: The RAMDRIVE.SYS file needs to be accessible from your floppy disk.  The best way to ensure it is accessible is to put it on your floppy disk.

2: Drive and path to the RAMDRIVE.SYS file.  So if it is on your floppy disk, it would probably be DEVICE=D:\RAMDRIVE.SYS 4096 /e

3: Expanded and extended memory are 2 different ways programs can access your RAM.  Windows uses Expanded memory, as do most programs.  There are some old Lotus programs, and a few really old DOS games that use expanded memory, but just about all programs written in the past 10 years will use extended memory.
sorry,i still don't understand bout extended and expanded memory..
what is the different on how they works..could you TELL me more...? thank you

one more.. if ramdrive.sys is in my floppy. i would just write device=ramdrive.sys 4096 /e ( no drive and path specified means that ramdrive.sys is on the root directory right.. it's in my floppy disk)
why you write D: on your example above?...For the difference between extended and expanded, try these links:

There is not really a difference between the actual memory (in most cases), but back in the "old days" before Windows, different applications had to be written to take advantage of RAM over 1 MB, and the 2 choices were Extended and Expanded.

You are right to QUESTION my use of the D: drive in my example.  That was a BAD example, and I should have used A:.  If the file is on your floppy disk you can use Code: [Select]DEVICE=A:\RAMDRIVE.SYS 4096 /e or EVEN just Code: [Select]DEVICE=RAMDRIVE.SYS 4096 /e assuming the RAMDRIVE.SYS is in the root directory of your boot drive.OK.. thank you very much for your nice help...
