Could you implement >8 drives too??? The system (DOS) can handle 254 drives
exept for one function. And this function is barely used. So drives A-Z
should be possible...
By the way, this non-supporting function is a >Dos1<-function call which
returns a value of which every bit corresponds to a drive (1=available,
0=not available). But even this function can be expanded to more drives. I
read in the official documentation that this is returned in HL and not only
in L. Therefor, it is possible to use 16 drives with this function!!! At the
moment H is returned 0 always, but it is preserved for more drives. So it
should be possible to return the next 8 drives here. And the last 10
drives... Well, those can't be detected using this function. A new function
has to be made for support of these.
This is what the manual says about it:
-------------------
3.25 GET LOGIN VECTOR (18H)
Parameters: C = 18H (_LOGIN)
Results: HL = Login Vector
This function returns a bit set in HL for each drive which is available,
bit-0 of L corresponding to drive "A:". Up to eight drives ("A:" to "H:")
are supported by the system currently, so register H will usually be zero on
return.
-------------------
The rest of the functions use a drive-number with the value 0 corresponding
to the default drive and values 1-255 corresponding to the rest of the
drives. Other functions use 0="A:", 1="B:" etc. Depends on the type of the
function call.
