(1) M-Systems Firmware Strange, but true. If I use M-System's DOS-based dformat utility to load firware version 4.2 into the DOC 2000 this prevents X from runnning from the IDE drive. This is true even if I boot with a kernel that has no support for the DOC 2000. As long as the DOC is sitting in my system (with Rev 4.2 firmware) X will not run. I should point out that X does not cause the system to hang in this case. (2) nftl_format So I bit the bullet and tried to remove all firmware (M-Systems dformat /empty) and then do a complete low-level format with the MTD nftl_format utility. Then I put on top of that a ext2 root filesystem (not self bootable of course). This provided no improvement. X still falls over at the same spot. (3) X Modules I then was able to look at the X log file (/var/log/XFree86.0.log) and it seemed that the point at which X fell over was when it was trying to load the ddc module (libddc.a). So I then mounted the entire /usr/X11R6/lib/modules directory from the IDE drive and ran the rest from the root filesystem on the DOC. This allows X to get a little further (seems to try to load a screen from the VESA BIOS). But it still hangs, this time after putting rubbish graphics on the screen (as in a normal initialisation). Question: Why does X have trouble loading the libddc.a module from the DOC? Thanks for you advice and suggestions thus far.

To go step-by-step through the lines of code, a debug version of xinit would be more helpful. I believe the gcc -g option will provide necessary debug information in the produced executable binary.
