33 mhz? Did you never upgrade it to 75 mhz?
75 MHz would be difficult on any early 33 MHz machine. You would have to change clock crystals, etc. Going to 66 MHZ with a DX2 or 100 MHz would be much more likely.
75 MHz was often slower in practice than a 66 MHz machine and was really only ever used to upgrade a fixed-frequency 486-25 when you didn't know how to change a clock crystal or the rest of the chipset was so old that it only supported 25 MHz FSB.
Yeah, most only needed one jumper so the other is usually in a 'storage spot'
Yeah, there are always places to stick a spare jumper so it will have no effect. The Maxtor recommended way for those model drives is illustrated above. This differs on other makes or other models of Maxtor, though.
For the yougins....
You set master/slave by setting the jumpers, IIRC windows liked to be the C: drive, so windows drive master second or cdrom etc slave. Or if it was ATA66 (IIRC) and you had a compatible cable (master connection = master drive, slave = slave drive) CS on the jumpers.
I don't know what you mean... Drive letters really have nothing to do with what the physical drive arrangement is. Windows has never cared what
drive letter you installed it on and back in the day, and back on early versions of Windows, when you had the 32 meg partition limit (especially in the MFM/RLL days,) without using something like OnTrack Disk Manager to get larger partitions, with a 40, or especially 80+ meg drive you already had at least a drive D:, E: or F:, never mind the letters on multiple drive systems. I usually installed Windows 286 on the D: or E: partition on my machines, for example.
Also, jumpers were required for things like setting the clock/voltage of the CPU.
All this new fangled automagic bios stuffs now.
It goes back a lot farther than clock/voltage.
On the original PC you had to set things like disk drives and memory configuration. Before that it was things like terminal baud rate or line printer interface card I/O address.
