Commodore A4000T troubleshooting

I read somewhere that workbench.library needs to be on disk, since it's missing in the ROM - that could explain why WB shows up, but never gets 100% working.

That's exactly it. I recently acquired an A4000T and the workbench.library needs to be in the Libs directory and if it isn't, the system hangs at workbench load. The original disk that came with the A4000T should have it on. My A4000T came with a SCSI system disk and I first transferred the original system to an IDE compact flash card/adapter combo and then did a fresh install of WB3.1 on another CF card. It hung just at the point where Workbench loaded with an empty workbench. I had to make a custom boot floppy with the workbench.library file and copy it to the Libs directory and it worked fine. I've had problems trying to get 2 IDE drives to work together on my A4000D. A hard drive and an IDE cd/dvd drive are no problem but I could never get the same CF adapter to work with the IDE drive at the same time in my A4000D. I got it to work by itself and transferred the system with Winuae to a 4gb CF card but it gave me data errors, even with the max tranfer rate correctly set. I gave up on it and went back to a 2.5" IDE drive.  It worked without any problems at all when I put it in the A4000T.

The procedure I used to install Workbench 3.1 was to make a custom boot disk with the O60 libs and workbench.library from a copy if the standard WB3.1 install disk. I had to remove quite a few of the install files to make room for it. You won't need the 060 libs but you will still need to delete some files. Once I booted the A4000T from that floppy, I removed it and inserted the full WB3.1 Install disk, did the complete installation, and reinserted the custom boot disk at the end and manually copied the workbench.library and 060 library files to the Libs directory.

There must have been a special set of install disks for the A4000T but I have no idea where to look for them.
