Sorry, Studio 13.37 only comes on usb. If converted to an iso image, many features will stop working.
As well, it may not be suitable for your scsi server PC.
Perhaps you should try Puppy Studio 3.3-rt
, from the creator of Studio 13.37. It comes with extra scsi drivers and is a CD-ready iso. (It does not, however, come with any support.)
Thanks and good luck.
