Hi Thomas

I have never done this, but I think 
BIOS  INT 13H,  can do the job
I dont have good documentation but I think the following function
will do the job !


GET DISK SYSTEM STATUS
INT 13h,   AH=01h,  DL=Drive 

READ DRIVER PARAMETERS
INT 13h,    AH=08h,  DL=Drive

TEST DRIVE READY
INT 13h,    AH=10h,  DL=Drive
