Hardware: IBM ThinkPad T23

1. create a maintance partiton on my primary HDD with bootabel 4.3

minium features: only boot to cmd prompt, no wps support
USB Support basic and USBMSD.ADD

Test the system - system is in Boot Manager Menue

2. take a CF 1 GB Card and create a partiton on the medium

How to it: readme.tx from LVM fixpak / Update 14.105 (XR0L002)

3. the PRM partition has a drive letter of C: in my configuration

4. xcopy y:*.* c:*.* /H /O /T /S /E /R /V

y: is the drive letter of the mini maintance system

5. \os2\install\bootdisks\sysinstx c:

6. modify the config.sys

1. drive letter Y: --> C:

2. Change USB statments in sequence and parm according
booting from USB diskette
souce of instructions:
- usbbasic package: USBBASIC.txt 14.162
- mcp2: Technote.txt

3. create an alternative config.sys with the original usb from
primary min maint partiton config.sys

7. boot from PRM

7.1 Activate USB BIOS support

7.2 change the startup/ boot seq in bios

The PRM is an Harddrive for the bios

set the primary hdd to the T23 inacitce in boot menue

8. The system boots from the PRM

8.1 OS/2 blob

8.2 Warp logo

8.3 the loaded driver are recorded

8.4 .

os2dasd.dmd
os2lvm.dmd

8.5 full screen mode

meassages from usb driver

meassages form dani driver

9. Error "OS/2 is unable to operate your hard disk or diskette drive"


Ths error shows up with config.sys

- with modified usb sequence

- with "normal, standard usb" statements

- with or without dani driver preasent e.g no driver for the
primary HDD


any ideas ????????? need help

Some things, that might help:

1) Use LVM, or DFSEE, to permanently attach a drive letter to your USB
drive. If you don't do that, the drive letter will, likely, change,
when the USB drivers do get loaded, and LVM takes control. The result
will be exactly what you describe.

2) Let bootAble build the whole system on the USB drive for you. I
have no idea why you would need to change what it builds. Doing a copy
of a system built on Y:, to C:, then expecting to simply change the
drive letter in CONFIG.SYS, misses about 90% of what needs to be
changed.

3) I remember, at one time, that OS/2 could NOT be booted from a
removable device (other than diskette). In the past, when I built
bootable systems on a removable device (an ORB disk), I used the /!RMV
parameter on the DANIS506.ADD line. That parameter tells the Dani
driver to report that the device is not removable. I don't know of any
similar parameter for the USB support drivers (if they need it).

4) You would, likely, want to make the USB drive startable, and put
the USB device boot before the hard disk boot, in the BIOS settings,
so that the USB device will boot, without needing the Boot Manager,
that may be on a non-working hard disk, at some point.

Hope this helps...
