HARDWARE INSTALLATION

Adapter Settings

first DM-8 installed, 388 for the second, 390 for the third, and 398 for the fourth. Refer to the System Adapter Appendix for jumper locations; refer to the following chart for the required jumper settings.

DM-8 Adapter (Address)	I/O Address Jumper Settings
1st adapter	J2,	J3,	J4
(address 380)	on, on, on
2nd adapter	J2,	J3,	J4
(address 388)	off, on, on
3rd adapter	J2,	J3,	J4
(address 390)	on, off, on
4th adapter	J2,	J3,	J4
(address 398)	off, off, on

Note: When the table says on for a certain pair of prongs (J2, J3, or J4), it means that a jumper needs to be in place for that pair. Off indicates that no jumper is needed for that pair.

DM-24 ADAPTER INTERRUPT AND I/O ADDRESS SETTINGS

The DM-24 adapter uses switches to set the interrupt and I/O address. Since the DM-24’s only available interrupts are 10, 11, and 12, and these interrupts are associated with configured slots 2, 4, and 6, these are the only slots available for these cards. Refer to the System Adapter Appendix for switch locations; refer to the following chart for switch settings.

Configured Slots	Interrupt Switch (IRQ) S2	I/O Address Switch Setting S3
2	IRQ = 11	Address: 300
	1, 2, 3, 4, 5, 6	1, 2, 3, 4, 5, 6
	off, off, off, off, on, off	A4, A5, A6, A7, A8, A9
		on, on, on, on, off, off
4	IRQ = 10	Address: 310
	1, 2, 3, 4, 5, 6	1, 2, 3, 4, 5, 6
	off, off, off, off, off, on	A4, A5, A6, A7, A8, A9
		off, on, on, on, off, off
6	IRQ = 12	Address: 320
	1, 2, 3, 4, 5, 6	1, 2, 3, 4, 5, 6
	off, off, off, on, off, off	A4, A5, A6, A7, A8, A9
		on, off, on, on, off, off

Note: The silk screening may vary from card to card. If your card uses the labeling DIS/EN or =1/=0, note the following: For IRQ, “off” is the same as DIS (disabled); “on” is the same as EN (enabled). For I/O address, “off’ is the same as “1”; “on” is the same as “0”.
