What is real lowest speed of PCI?



Hi,

According to PCI specifications v2.2, any 33MHz PCI device must support
bus speed from DC to 33MHz. What a bizarre requirement! Can any PCI
device really work in DC? But if you don't, your device is not PCI
compliant! Old spec clearly defined the lowest speed, 16MHz. But what is
the lowest speed you are "supposed" to support for v2.2?

Most mother-boards on the market just implement 33MHz PCI buses.
However, lower speed PCI slots do exist. What is the lowest speed on the
market?

Nobody seems to be interested in extremely low speed. People simply piss
off the spec and still claim PCI compliant, or my understanding in
incorrect?
