Hi George
1] Bootable uses whatever drivers you have installed; LVM is optional.
2] The USB drivers supplied with 4.51 do not work very well for mass storage devices; they need updating.
3] The even older CW USB drivers may be of some use but from posts I have seen they are not as much use as the last IBM USB driver release.
4] Bit surprised you do not get errors during boot with a config.sys usb section like that :-)
Either use the CW driver or the IBM driver but not Both versions of the same driver - you may also want to check what USB Controllers and how many are involved.
I suggest updating all IBM USB and IDE drivers plus Danis506.add and daniatapi.flt drivers to current levels for at least the system that you are trying to create this CD on.
Once you have functioning USB Mass Storage support create a Bootable CD without Desktop or networking support. With luck it will work to boot all similar (near identical hardware) systems but the CD/DVD drive letter needs to be exactly the same on all systems ie if you create a Bootable CD in drive S: then that CD will only work in systems that have S: as the CD/DVD drive letter.
If you decide to update the IBM USB drivers USBcfg could be of help in getting USB configuration correct
