Adaptec Jumper setting for AHA-1540B/42B

I need to know how to set the jumpers on an Adaptec AHA-1540B\42B board.  Adaptec doesn't support this board any longer so they don't have the documentation at their web site.  It would take too long to send for the info.  I need an answer today.  I need to set the SCSI ID physically on the board from 7 to 6 so it won't conflict with another Adaptec board which must be set to 7.

Please try to get back to me today.

Thanks much,

Gary Kambic

I'm assuming you're running Win95.  It should automatically detect and configure your boards properly.  You don't need to change the SCSI ID#.  You just need to set the IRQ and I/O's properly.  You will actually have TWO seperate SCSI chain's.

If you are running DOS, just run EZSCSI and you should be able to set it up easily.  EZSCSI does an excellent job of detecting and configuring your SCSI devices.  SCSI cards are mostly set to always take up ID#7.

This should take care of it.  Hope this helps.

does the hit ctrl a message appear when the board is initialized?  This feature allows to configure various settings on the board.  I don't bleieve this is a pnp board, so irq, dma, scsi id and i/o are all controlled from this menu.

I got the documentation from Adaptec.  The settings are on the board.

Thanks,

JoeCool is correct. Please DO NOT chage the IDs! I work for Adaptec TS. Since each board is its OWN seperate SCSI chain, each board will support the full set of IDs 0-7. There are MANY situations/applications that the controller MUST be on 7.
This board is set strictly via Jumpers (pretty old..., but good!)
