CSCF Boot Disk

• Note Work in progress

What

• Provides a network boot floppy (or CD) allowing network access to a file server for image deplyment
• Based on the "The Universal TCP/IP Network Bootdisk" from http://www.netbootdisk.com/

Where

• Local CSCF updated copy can be found at \\asimov.cscf.uwaterloo.ca\exports\export_dos\netboot

Why

• We needed a network boot disk that was easier to maintain and update then Bart’s Boot Disk
  (A very capable but complex boot disk - full of spaghetti code and gotos with little internal documentation)

Theory of Operation

Files

• config.sys

     - uses tunz.com to extract boot.zip and creates 32Meg Ram Disk as Q:

• boot.zip

     - contains command.com and UHARCD.EXE

• autoexec.bat

     - starts from command.com (boot.zip from config.sys)
     - copies FILES.UHA and script.bat to Q: - ram disk
     - starts Q:\script.bat

• script.bat

     - copy user preferences saved in menuperf.bat from floppy to Q: ram disk
     - extract (uharcd) FILES.UHA to q: - ram disk
     - starts Q:\bin\script2.bat (from FILES.UHA)

• script2.bat

     - starts menu interface with timeout
     - starts network and other services
     - restores user preferences running menuperf.bat
     - starts optional user scripts as defined with menu

Master Menu

• Note: by default the manu menu will time out and execute the default boot script after a short timeout
  • With this menu you can change
    • How driver are loaded
    • Default Userid and Password
    • What post boot scripts will run (ie a script to run - (See Example Scripts)

Example Scripts

• <!>FileCopy\cscf.bat - Map network drives

   @echo
   Rem EXPORT
   net use x: \\server\exports
   set path=%path%x:\bootdisk\bin;x:bootdisk\pqdi.550;

   Rem Nexus
   net use n: \\server\nexus

   Rem Core
   net use o: \\server\core

   Rem Sysprep
   net use s: \\server\sysprep

   Rem Optional Post Install Script Example
   REM n:
   REM cd \net
   REM call install.bat

• n:\install.bat - Nexus Automatic Install batch file

   Echo Installing image on First Hard Drive
   pqimgctr /IDE=ON /CMD=N:\net\LAB.TXT /NOAFX

• n:\LAB.TXT - Nexus Automatic Install script ( See PowerQuest for more technical information )

   SELECT DRIVE 1
   DELETE ALL
   Set Image Filename 'N:\4SEP2005.PQI'
   SELECT FREESPACE FIRST
   SELECT IMAGE ALL
   RESIZE IMAGE PROPORTIONAL
   RESTORE
   SELECT PARTITION 1
   SET ACTIVE

TODO

• Add Screen shots
• Document steps to add drivers and rebuild disk image
