Minimum mode describes a chip configuration where the 8288 bus controller is not required. Certain signals, such as ALE, are then generated directly by the processor. Maximum mode describes a chip configuration where the 8288 bus controller is required. The 8288 generates ALE, and other signals, allowing the processor to provide other signals, such as LOCK. These two mode allow the system designer some freedom, and allow the number of pins on the chip to remain lower.
The SM Bus (not bus) controller is also known as the System Management Bus Controller. It is part of your computer's motherboard chipset drivers. If you need to install chipset drivers, you need one that is compatible with the SM Bus controller.
The data and address buses are multiplexed in order to save pin count on the chip. In the first clock cycle of a read or write cycle, the address is emitted on the address/data bus. The ALE signal is used to strobe the address, after which the address/data bus becomes the data bus. External logic is expected to strobe the address at the trailing edge of ALE. ALE is generated directly by the 8085, and by the 8086/8088 in minimum mode. In maximum mode in the 8086/8088, ALE is generated by the 8288 Bus Controller.
Minimum mode in the 8086/8088 provides the functionality of the 8288 bus controller, which means that functions like HOLD, HLDA, WR-, M/IO-, DT/R-, DEN-, ALE, and INTA- come off of the 8086/8088. Maximum mode means that these functions come off of the 8288, in somewhat enhanced form, and the pins are replaced with new meanings like RQ-/GT0-, RG-/GT1-, LOCK-, S2-, S1-, S0-, QS2, and S21, giving the processor extra capabilities.
The SM Bus Controller, or System Management Bus, is installed on the motherboard. It was developed by Intel. It varies on the specific place according to the motherboard.
There is no maximum pin in the 8085. In the 8086/8088, however, there is a min/max pin, called MN/MX-, that is used to configure whether certain bus control signals are provided by the 8086/8088, or by the 8288 bus controller. In the latter case, this frees up several pins for other, more sophisticated, i.e. maximum mode, uses.

A bus controller typically comes with an adapter if the word "adapter" is included in the product title.
Local I/O Bus
SM Bus Controller is the generic reference for the system board main chipset of Microsoft Windows XP. This can be found on the uninstalled chipset driver.
