Changes:

  • Added support for the Silicon Valley Computer ADP50L controller (and possibly other IDE controllers from SVC using memory mapped I/O). Please note that this has not been tested in any way since I don't have any of these cards myself (make backups before trying this on drives with important data). Also, *if* it works, make sure it works reliably (stress test the disk system). Some things you should know: 1) Autodetection for this controller has not been added to XTIDECFG, you need to manually select the "SVC ADP50L" controller (and possibly change the BIOS segment address if not using the default of C800h). 2) The memory mapped I/O window is inside the ROM address space of the controller. The XTIDE Universal BIOS currently do not support this so that means you need to use another ROM (for example, an XTIDE or XTCF card or the BOOT ROM of a NIC). This presents another problem, the original ADP50L BIOS needs to be disabled somehow to avoid conflicts. Either pull the ROM chip or disable the BIOS by removing jumper J3. Note, I have no idea if any of this will actually work. It's basically a shot in the dark.
