It should be sufficient to read DEVLOAD's source code for that. I looked into that stuff some time earlier (last year? or 2009?). Might have told Eric about it back then, too. In any case, I don't have my files or archived mails with me right now (not at home), but downloading DEVLOAD 3.21 and skimming the source code it would appear to me as if you would have to look into devload.asm around line 1360. Additionally, pay attention to where ever else it uses LastDrUsed or LastDrive. The check at around line 1300 probably has to be extended to search for a free CDS entry, and use that if found. While you're at it, you might review all phrasing that uses terms like "LastDrive array" in the comments - that appears to be a confusing way to refer to the CDS (array). The trickiest part about this patch is figuring out what to do with the List of Lists field referred to via the LastDrUsed variable here - this is supposed to be the count of installed block device units/(E)DPBs, but if there's non-consecutive (E)DPBs with redirector/CDEX CDS entries between them, should that counter reflect the number of actual (E)DPBs, or the (1-based) index of the highest (E)DPB? (Limited compatibility with programs that, like DEVLOAD currently, presume there are only (E)DPB-based CDS entries could be achieved by making it equal the index of the highest (E)DPB-based CDS entry. On the other hand, first, these programs are wrong anyhow, and second, I have a feeling that it should be the count instead. Oh well.) Unrelated: the software list says that the most recent version of DEVLOAD is 3.22, but I couldn't find that right away. Is that an error in the software list or did I just not find it?
