by 16 bits.
Local ROM
Firmware for the 80186 Microprocessor is stored in the ROM. The ISC card ROM contains either
16K bytes configured as
BK
by 16 bits or 32K bytes configured as 16K by 16 bits. The ROM is accessed
via the Upper Memory Chip Select (UCS[O]) and address bits 14-00.
CM 195T Equipped Device Table Data
The following table shows the Equipped Device Table (EDT) data for an ISC card. A value of 0
means NO; a value of 1 means YES. The indirect device (indir_dev) is only applicable to systems
equipped with Small Computer System Interface (SCSI). The request queue size (rq_size) and the
completion queue size (cq__size) are ISC software defined values. As such, the rq_size and cq_size
values may differ between versions of ISC software.
