External 150MB Archive Streamer

Some problems have been encountered with our previous recommendations on settings for the external Archive 150MB tape unit. We have therefore re-examined the settings and would now suggest the following options in addition to those detailed in IPB 3123.

For XEN-S / XEN-LS running SCO Xenix 2.3.4, configure the hardware jumpers as described below:-

(A)	IRQ							DRQ			DACK
	1	2	3	4	5	6	7	1	2	3	1	2	3
	off	off	off	off	ON	off	off	ON	off	off	ON	off	off

(B)	BASE I/O PORT ADDRESS
	ON	3
	ON	4
	ON	5
	ON	6
	ON	7
	off	8
	off	9
	ON	10

Now carry out the following commands in Xenix:-

cd /usr/sys/conf

./configure -c -d -m 6 -v 5

Now run mkdev tape setting the values as given below:-

	Card Type:	1
	DMA Channel:	1
	Interrupt:	5
	I/O Port address:	0300H

Some revisions of reference disk do not provide the option of 310H documented in IPB 3123 for I/O port address on MCA machines. Should this be the case please use 0308H and modify the software installation correspondingly.
