er.. just plug in the damn thing. then use hdinsttools, but DO NOT FORGET to add something like device=oktagon.device in tooltypes or commandline of hdinsttools.
Do you have some HDD and hdinsttools on it? If not, make a bootable diskette with it and with PFS-060 in l:
(if you have pfs and 060)
but I'd check oktagon specs on internet first. When I used it with A4000 (060) it was so slooooow. It doesnt have DMA. Builtin IDE might even be faster!!?? On the other hand if you must connect scsi devices(?), and dont have fastlane..
PS, I could burn CDR-s on oktagon but only x1 IIRC or maybe x2.
