DMA x Reserved for Legacy Drive [No/ICU]

These fields indicate whether or not the DMA channel displayed for each

field is being used by a legacy (non-PnP) ISA card. The default setting

indicates either that the DMA channel displayed is not used or an ICU is

being used to determine if an ISA device is using the channel instead.

Configuration options: [No/ICU] [Yes]

TSM MEM Block BASE [No/ICU]

This field allows yout to set the base address and block size of an onboard

legacy ISA device that uses any memory segment within the C800 and

DFFF address range. With such a device, select a base address from the

options. If an ICU is already in use, then leave the TSM MEM Block

BASE to its default setting of [No/ICU]. Configuration options: [No/ICU]
