Unable to copy *.RMI files during Win2000 Setup

[driver.au]

I'm in the process of making a slipstreamed/unattended Windows 2000 Professional CD-ROM.

The CD boots to DOS, does pre OS partitioning, formatting, etc, then runs windows setup in unattended mode using winnt.exe /s ... /u ... etc (Why DOS, and not extracting the Win2k CD bootsector? -- I want the ability to run my own Pre-OS Questions/menu interface to adjust the unattended file on the fly. )

Now all works good, until the 2nd phase of file copying during the text mode setup. It compains that bachsb~1.rmi along with many other *.RMI that they can not be copied. However the files are actually on the CD (in *.rm_ compressed form) like they were on the original CD - which worked fine.

DOS 8.3 ~1, ~2 filenaming doesn't appear to be broken either.

Any one know how to fix this?

Or know how to remove the files alltogether? These are only BS MIDI sample music anyway
