TR-DOS with ramdisc for all 1MB ZX clones

[VELESOFT]

VELESOFT , is possible to integrate a token/command which changes the letter RAM-DISK instead of "D" for "A" into TR-DOS6.11Q? there are programs with "drive A only" problem.

and back on "D". value of a variable can be stored in GLUK CMOS.

CMOS is usable only on some clones. I use this trdos without real FDD and ramdrive is "A". And work more programs with access only to "A" drive :-)
I can add CMOS support from orig. version 6.11E...
Make new command for change RAMDRIVE number is possible, but I don't know this routines in tr-dos. If anyone can help with this feature.... This command must write one byte with ramdisc drive number to system variables in zx ram(we must find one free/unused byte), but if any software rewrite this byte, trdos can see incorrect ramdisc drive number... :-(

One idea: we can save tr-dos setup also to 1MB ram. For example at begin of 16th ram page = first 256kB ram(ram pages 0-15) is full usable for ZX software with 256kB support. Next page(page 16) at begin contain setup = word "cfg:"+bytes with ramdrive and similar setup. If this "cfg:" text are not detected then tr-dos can use default tr-dos setup (ramdisc on drive "D")
