Burst Nibbler?

Hi all, Have a friend that has acquired a heavily optioned up Commodore 64. He is not very clued up on computers in general, but he has some strange options fitted. There is some sort of accelerator board built in to his 1541 drive. Unfortunately, for it to work, it evidently needs a disk with something called (I think) Burst Nibbler on it. Seems to be associated with something called Dolphin DOS, possibly on the same disk. Problem is that he doesn't have the disk, seems he bought the machine and many boxes of disks at auction, but a pile of other disks went to someone else. He was able to find the original owner, who confirmed that he needs this particular disk to make the fast loader work, but it seems it was with the stuff he didn't get.. I know just enough about C64's to avoid them like the plague, however I would like to help him if I could.. Anyone out there know more about this, especially in Oz? I'd be happy to cover the costs of copying/shipping a floppy. Cheers Geoff Roberts Computer Systems Manager Saint Mark's College Port Pirie, South Australia.
