I have a BBC Master 128 with the standard ROM installed. This includes ADFS v1.50 in slot "D". I want to replace this ADFS in ROM with a patched version, loaded from disk, into Sideways RAM. It is a 16K .bin file. The patched version is needed to support my IDE interface. I think the standard ADFS in ROM just supports SCSI.
It seems I can UNPLUG the ROM version of ADFS, but I haven't found the right command to replace it using SRLOAD. I don't know which address to use or what ID to give it.
What would be the correct sequence of MOS commands (or, better, OSCLI commands that I can put into a BASIC program)?
