1. Wipe the device, shutdown, reboot
2. Formatted as PRM with one partition C: FAT with the mini OS/2 system.
3. For the installation of GRUB the "GRUB Boot Directory" is made on the C: drive.
  
  c:> md boot
  
  c:> md boot\grub
copy the file menu.lst to the "GRUB Boot Directory" - listing of the file is in SubWiki menu.lst

boot the system from the Knoppix 5.1 CD
Mount the CF Card - GUI Operation
Grant write access to the CF Card - GUI Operatiom
Open the "root command window" ( root shell ) - klick on Trux icon in the task line
Copy the files from the "GRUB Image Directory" to the "GRUB Boot Directory" on the CF Card

[Edit]2 Test results menu.lst 1. Version

The system boots form USB MSD
GRUB is start and the selection Menue is presented

 1. OS/2 USB PRM Boot Drive Letter C: LVM System FAT /VFAT

 2. OS/2 Boot Manager - 14.105 May 2006

 3. MBR IBM OS/2 LVM, 14.105 May 2006, I13X  on primary HDD


Selection 1: "OS/2 USB PRM Boot Drive Letter C: LVM System FAT /VFAT"

 OS/2 blob, the OS/2 System is loaded

 after loading / installation of OS2LVM.DMD

 Boot process stops with "OS2 can not access ...."


 Possible reason: No boot drive letter and boot device type in LVM process "removable"

 The Chainloader of GRUB loads the partition BR like the IBM BMGR, but does not pass an boot drive letter 


Selection 2: "OS/2 Boot Manager - 14.105 May 2006"

 The Chainloader of GRUB loads the partition BR of IBM BMGR partition, the IBM BMGR stopps with eror message 


Selection 3: "MBR IBM OS/2 LVM, 14.105 May 2006, I13X  on primary HDD"

 The Chainloader of GRUB loads the IBM  LVM 14.105 MBR and start executing the bootcode.

 System stops with SYS01463
