How to creat a CD-ROM environment variable

[Rico.JohnnY]

i find a post below...but i am not sure about how to use it in a RunOnceEx.cmd file.

http://www.msfn.org/board/index.php?&showtopic=10798&hl=

i tried time and time again..but still didnt work.i used the %CDROM1% variable and installed my apps from a CD,but every time in RunOnceEx setup, an error occured,and the CD drive part of an app's installation path seemed to be blank..

why was that?

unattended.msfn.org suggests the following for runonceex.cmd (with marker CD.txt on the CD)

IF EXIST D:\CD.txt set CDROM=D:
IF EXIST E:\CD.txt set CDROM=E:
IF EXIST F:\CD.txt set CDROM=F:
IF EXIST G:\CD.txt set CDROM=G:
IF EXIST H:\CD.txt set CDROM=H:
IF EXIST I:\CD.txt set CDROM=I:
IF EXIST J:\CD.txt set CDROM=J:

Same results can be achived with

FOR %%d IN (c: d: e: f: g: h: i: j: k: l: m: n: o: p: q: r: s: t: u: v: w: x: y: z:) DO IF EXIST %%d\CD.txt SET CDROM=%%d

but i want a permanent one..

you'd have to import the settings into the session manager via Registry tweaks.

SETX may prove to be helpful as well.

Look at the bottom of this page.

I use the following two lines in my runonceex.cmd file. They are two variables I find useful.

SETX CDROM %~d0 -m
SETX DEFAULTUSERPROFILE "%USERPROFILE%" -m

You can get setx off the xp cd, in the support folder. The CDROM one is only useful if you plan on using the xp cd for installations. Otherwise, using the if cdrom, blah blah works.

on mine, it is under

support\tools\support.cab

look for setx.exe

[Rico.JohnnY]

SETX CDROM %~d0 -m

it does not seem to work...what does the %~d0 stand for?

i use a DVD rom..so how to configure the variable to match my own CDROM?

It has to run in a cmd file and on the CD/DVD. I put this command in my runonceex.cmd file, which i call with command lines. You can put it in another cmd file if you wish, but it has to be on the cd.

%~d0 is a variable. It says give me the drive of the first arguement, which is the script.

so...do i have to copy the setx.exe to system32 folder during setup?

It would have to be in your path somewhere. I generally throw it in system32.
