I was wondering if anybody could help with the following questions/
problems re: the Seagate ST-02 SCSI host adapter:
	(1) Fastback Plus seems to flinch.  I can only use "Low DMA
speed" with the ST-02, where previously I could use "High."  Why?
	(2) IAU19 does not work.  Does anyone know of an interleave
adjustment utility which works with the ST-02/SCSI?
	(3) The ST-02 has a jumper for enabling interrupts (either IRQ
3 or IRQ 5).  The manual advises keeping interrupts disabled.  What
does this jumper do?  Why does it exist?
	Any other tips are most welcome.  I will post a summary of
responses if interest warrants, so please reply via net mail.
