In my RLX-B with the ADP-50, the drive list is as follows:
Out of curiosity, what are you using to grok the int13 drive assignments? I tried Checkit 3 and Norton Sysinfo 6, and neither seems to tell you that particular piece of info. I can confirm after switching the SD card that has Tandy 3.3 on it back into the HX that my memory that the ROM drive shows up is correct; if I use Norton to check out what disks are available there's not hide nor hair of it under PC-DOS 7, while under Tandy 3.3 it shows up as a 47k D: drive between the C: and E: drives (C: and D: under DOS 7). It's been a while but my vague recollection is if you had two hard disks the primary partitions on the two physical drives would show up first, followed by the extended partition drives, so I assume it must be assigning the XTIDE drive as 80h and ROM as 81h or higher... but again, only seems to happen with Tandy's DOS.
