4The enhanced graphics adapter (EGA) and 3278/79 Emulation adapter may be used together; at this printing, there is no
known program that uses interrupt level 9 on the EGA.
sThe 5080 attachment adapter and the S/370 host interface adapter are designed to operate together at the defined default
values. If these adapters are reconfigured for the other optional DMA channels, the user must provide driver/application
software.
6DMA channel 3 is only required when the PC Network Adapter is used with the Personal Computer AT Coprocessor Option.
7The AIX operating system restricts serial port A (2) to use of DMA channel 0; DMA channel 2 is used by the diskette adapter.
DMA channel 2 may be available when other operating systems are used.
sDMA Channels 5 and 6 are not supported by IBM software.
