I'm not sure if the WinDDK is what you would call .Net. The
link above is NOT VB6 (nor any other BASIC). The link
does provide a working RAM drive for XP systems (and I
believe Win2K as well, but I only tested on XPSP2). It also
provides a DLL to manage the size and drive letter for the
RAM drive. Both the ramdisk.sys and the ramdisk.dll come
with source code and whatever language it's called, it's some
sort of C++ with extern "C" implementations.
Also, I changed the name of ramdisk.sys to ramdisk1.sys so it
wouldn't interfere with XP SP2 ramdisk.sys (in case of SFC
protection). I modified the ramdisk.inf file to use the renamed
ramdisk1.sys during it's installation and it worked great without
a glitch.
The modified ramdisk.inf file is posted under my sig.
I couldn't get the RAMDisk supplied with ServicePack2 for
XP to work and gave up on that.
So if anyone wants to create a RamDrive...
1) Grab the files (binary and source code) from the link above,
2) Unpack the files,
3) Rename the ramdisk.sys to ramdisk1.sys,
4) Open the ramdisk.inf file and copy the stuff below over
everything, or just do a search and replace ...
search: ramdisk.sys
replace: ramdisk1.sys
5) Follow the steps at the link above for the rest of the install.
Hope this is worthwhile for anyone that wanted to set up a
RAM drive.
