^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 322) name of a bus system, i.e. the way the CPU talks to the other stuff
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 323) inside your box. Other bus systems are PCI, EISA, MicroChannel
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 324) (MCA) or VESA. ISA is an older system, now being displaced by PCI;
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 325) newer boards don't support it. If you have ISA, say Y, otherwise N.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 640) minimizes latency, whereas a low frequency minimizes overhead of
