Unattended Secret: Reducing Size Of Source

Recommended Posts

You only need the ic files if your cd has xp home edition i believe. I always include both the ip and ic files.

I tried to keep my first post as simple as possible so people didn't get lost. Hopefully i didn't lose anyone. For those people who successfully made the slimmed down xp cd, let's take it a step further.

Most people making unattended cd's just try to make a typical cd that just installs stuff such as software and hotfixes. They read microsoft articles on making unattend files, slipstreaming, etc and they stop there. But once you've made an unattended cd you have a problem: you can only use the cd for unattended installs. You cannot use it for recovery console or to repair XP. You also can only use 1 unattend file, you can't have multiple unattend files. Let's take my original post further so you can use the cd to make an unattended install, -OR- use recovery console or repair XP.

I'm going to assume you've already followed my first post and still have c:\install

First, rename the BOOT folder to VOL1. Then copy the contents of the VOL1 folder to 2 other folders - VOL2 and VOL3 (make sure VOL1, VOL2, VOL3 are capital letters). SO VOL1, VOL2, VOL3 should all have the same files and be the same size. All 3 folders should be in c:\install

Next, hex c:\install\VOL1\setupldr.bin, replace BOOT with VOL1, the hex editor should find 4 matches (you might need to make a brand new setupldr.bin file if the hex editor finds more than 4 matches). Then hex c:\install\VOL2\setupldr.bin, replace BOOT with VOL2, the hex editor should find 4 matches. Then hex c:\install\VOL3\setupldr.bin, replace BOOT with VOL3, the hex editor should find 4 matches.

Make sure VOL1 doesn't have a winnt.sif file. Put your unattend file into VOL2. Ignore VOL3 for now.

Rename xpboot.bin to VOL1.DAT (all capital letters). Copy VOL1.DAT to VOL2.DAT and VOL3.DAT. So we should have VOL1.DAT, VOL2.DAT, VOL3.DAT, that are all identical. Hex VOL1.DAT and replace BOOT with VOL1. Hex VOL2.DAT and replace BOOT with VOL2. Hex VOL3.DAT and replace BOOT with VOL3.

Now download http://www.nu2.nu/nu2files/diskem1x.zip and extract the file to a temp location. From this temp location, copy these files to your c:\install folder:

Deload.bin, diskem1x.bin, loader.bin

Copy what's below and save it as c:\install\diskemu.cmd

;

:boot

cls

print

print Press Enter to boot from CD...

getkey 5 esc

onkey esc boot 80

onkey entr goto start

; When no key found...

goto boot

:start

cls

print

print ------------------------------------------------------------------------------

onkey 1 run VOL2.DAT

onkey 2 run VOL3.DAT

onkey q quit

onkey x goto dev

onkey f1 goto help

onkey esc boot 80

print Hit the key "d" will bring you to the hidden Development menu  ->

print Press any key to return to main menu...

getkey

goto start

; EOF

Ok so now in your c:\install folder you should have the following:
Directory of c:\install

10/08/2003  06:58 PM    <DIR>          .

10/08/2003  06:58 PM    <DIR>          ..

10/08/2003  06:58 PM    <DIR>          I386

10/08/2003  07:52 PM             2,048 VOL1.DAT

08/23/2001  09:00 AM                10 WIN51

08/23/2001  09:00 AM                10 WIN51IC

08/23/2001  09:00 AM                 2 WIN51IC.SP1

08/23/2001  09:00 AM                10 WIN51IP

08/23/2001  09:00 AM                 2 WIN51IP.SP1

08/23/2001  09:00 AM            11,387 SPNOTES.HTM

10/08/2003  06:58 PM    <DIR>          VOL1

08/23/2001  09:00 AM             2,980 DISKEMU.CMD

08/23/2001  09:00 AM               512 DELOAD.BIN

08/23/2001  09:00 AM            12,288 DISKEM1X.BIN

08/23/2001  09:00 AM             2,048 LOADER.BIN

10/08/2003  07:52 PM             2,048 VOL2.DAT

10/08/2003  07:52 PM             2,048 VOL3.DAT

10/08/2003  11:38 PM    <DIR>          VOL2

10/08/2003  11:38 PM    <DIR>          VOL3

That's it. Now let's build it with cdimage.exe:

cdimage -lXPSP1 -t08/23/2001,09:00:00 -bc:\install\loader.bin -h -n -m -o c:\install c:\xpsp1.iso

You now have a bootable XP Pro SP1 cd. When you boot from it, if you chose option 0, it's just a regular xp install. You will be able to use recovery console, repair xp, and you can chose every option in xp seteup. If you chose option 2, you will do an unattended install. If you do option 3, it'll do whatever you want it to. In my example, i made it an OEMPreinstall.

gosh, forgive me for saying this but one can cut down the size of the i386 folder to 340 megs without going through the lengthy prcedure you are describing. the LANG folder can be safely deleted among other things for example. some cab files can be removed also by taking your INF method a step further (test results on this soon). scancurban mentioned a method of creating silent rar sfx archives for themes and other apps to cut down the total size of the cd.

Very interesting. Is it possible to know which files from language subdirectory is required for a particular language so I can copy only those files to my cd?

Well of course if you manually delete files on your xp cd it'll reduce the size. The reason i use my method is because it's quick, it allows you to use several unattend files, it saves 150 megs, and it'll cause no problems.

Using my method is exactly the same thing as running winnt32.exe and doing a clean install. Manually deleting files, deleting folders, could cause unforseen problems. And my way you don't remove any features. When you manually remove windows media player and stuff like that you are removing features, mine is feature complete. Also compressing files using winrar will cause setup to take longer as it uncompresses the files.

And even if you make a huge batch file that removes hundreds of files from the xp install, you still won't have access to recovery console using an unattended install, or have the option to repair XP.

One question...

I have made an unattended CD without deleting any of the original files. I have only altered the winnt.sif. The disk will not display the recovery console nor allow me to repair an existing XP installation.

This is my only problem with my unattended disk. Do you know how I'd fix that? It must be an entry in winnt.sif, can't think of anything else.

If you are using an unattended file there is NO WAY to access recovery console or repair xp. If you look at my 2nd post i describe how to get around this.

@gosh

does it run with a real unattended installation not over cd with winnt.sif?

I'm connecting to a share and run

set ntpfad=v:\i386
%ntpfad%\WINNT  /S:%ntpfad% /U:%ntpfad%\_unat.txt /UDF:ue%ANS%,%ntpfad%\_udf.txt /E:C:\winnt\install2.bat

via this method, the setup have 2 parts for copy files

thx

This is something i am going to try as i like the idea, But i have one question for you.

When is the HAL created?

If it is in the stage that creates the two folders then this process is only good for the pc it is created on.

If it is after that then all is well and it can be used for all pc's.

Can anyone give any details on the HAL and when it it created as this is something i don't know much about.

I've followed your guide gosh and Setup still goes through textmode setup before continuing GUImode setup. Should that be happening? Also, when I tried to run winnt32 with the unattend switch it told me that my winnt.sif was invalid. Any ideas?

I tried this with the same result.

When i use 'winnt' unter DOS, the 2nd folder is created.

No explanation to this behavior...

Be careful with editing the Diskemu.cmd:

Never use TAB and never leave spaces at the end of each line,

the batch will NOT run.

You get a BAD COMMAND ERROR !

And don't forget the EOF at the end of the script.

If you burn with Nero:

('cause cdimage.exe is "For internal use only" and don't burn)

Bootfile is loader.bin

No Emulation

Segments 4

...like normal XP-BootCD

Summary, i use this GREAT method to have the opinion to include a WIN98SE-BOOTDISK

to create partitions with Xfdisk or other tools.

Let me do a little more explaining.

You should only run winnt32.exe /noreboot from the GUI. When you run this command, all setup does is copy files using dosnet.inf. Then it restarts your computer and runs setup from your hard drive.

If you look at the ~LS folder you will see several files are not there, such as winnt32.exe and winnt.exe. Microsoft's documentatioln says that when you boot from an xp cd, winnt32.exe is launched. As you can see, this is not true. Using my method our cd won't have winnt32 or winnt. When you boot from cd, setupdd.sys is run (text mode setup). After rebooting into GUI mode, syssetup.dll is run under the setup.exe process.

You can only use this method to install from CD, since there is no winnt or winnt32. And like i said you can only do clean installs, not upgrades.
