whoa, first of all, if you have some REAL cheap, from a friend, to a friend
me, send a bucket over, i ll pay you back for the freight and some beer drums (full and chilled ones, of course). i found a price tag of 550 pounds sterling, and thats many many euros and even more dollars
about the idea, the data flow would not be a bottleneck there, but rather a cpu or ram, in case you get lucky and have it work.
in case the motherboard is SO old, it wont be having not even usb gen 1, but only a pci raiser/card could work, maybe, in case you get lucky with the bios. if not, then some old lilo stuff maybe, then get transfered to cd or straight to pci storage (your usb mounted stick).
dont think the cable ide to usb reversed would work, since no drivers on dead system to use the usb, and you WOULD need to manually amend the wiring, i guess (im not familiar, but thinking the worst case, like send receive, ground etc like in serial/parallel/LAN cabling).
maybe, just maybe.
btw, i had to check on the kingston home that 256gb stick was not a hoax
damn, its true, and i thought my 32gb survivor meant business
(keep forgetting its an almost 2 year deal now)
so, as i said, id go lilo, if i remember well, since no cd boot was available on the rig i was playing with, that would hand over to cd, once drivers there, kernel on cd, forward to usb (just brainstorming now).
anyway, the data thruput and the overall usability of the machine that old is IMPOSSIBLE to use well of the 256gb. one more, if youre lucky, you dont get data storage size limit in bios
he he, have mighty fun, italians would say, rompi coglioni on this one
