Yeah, I am not doubting the author at all, but I built a lot of computers for myself and others in the 90s, and maybe I just don't remember, or maybe I always had two cables, one for each drive, but I distinctly remember setting jumpers and it just worked. That said, I was using mostly Linux, sometimes Windows, so maybe this was an OS/2 thing? Something I do remember though, was having to get the blocks, cylinders, etc... manually when partitioning/formatting disks. I guess I got lucky with the drives I used, which back then would have mostly been Western Digital with a splash of Seagate, maybe because I didn't typically mix vendors in an initial build I just didn't run into these issues.
