Change Drive Letters in Win NT 4.0

I'm trying to change the Zip100 Drive Letter from D: to B: in Win NT 4.0, but I can't find the way to set the drive letter in Administration Control.

Omega Zip 100 Drive is set as Master and CD-ROM Drive is set as Slave. Only way to change the Driver Letters is to change the jumpers on both drives. Problem is I don't want to do that on all 30 computers!!! Come on, there's has to be a way to manually change the Drive Letter in NT 4.0.

Anyone know how?? Help me!!

 

I thought A: and B: were reserved in the BIOS for floppy/ls120 drives?

What SP level are the NT machines?

 

Cannot Change the Drive Letter of Removable Drives

 

Yeah.....I enabled it in the BIOS, but still Zip 100 still show as Drive D:

SP? Are You asking me what Service Pack NT 4.0 using? Well, I upgraded them to SP 6a.
