Yes, but what I don't know is:
Does it stop _all_ drives server by that DiskROM or does it take some kind
of parameter? It could be that the 8250 DiskROM does more than it should
do. I have no documentation for this call, what I know is from disassembling.
One document even describes #401F as "nothing (RET)". This was probably
someone disassembling as well, but on a Sony instead of a Philips.

Thanks for the warning.
By the way, do you know a way to find the DiskROM slot ID for a drive under
DOS2? Under DOS1 you can use the #FB21 table, but I doubt that will work
under DOS2, which supports re-arragning drive letters, gaps in drive
letters (A,B,H) etc.
