Adding SCSI host adapters and peripherals

Adding SCSI PC Card host adapters

Note the following configuration issues if you are using a SCSI PC Card host adapter:

For the Adaptec SlimSCSI 1480 CardBus adapter, use the alad SCSI host adapter driver.
For the Adaptec SlimSCSI 1460 PC Card adapter, use the smad SCSI host adapter driver.
If the default IRQ or base I/O address do not function, try using a different IRQ and the alternate base I/O address:

0x340 - 0x35f

NOTE: If you need to change the default IRQ setting for the Adaptec SlimSCSI 1460 adapter, you will also need to make a change to the smad driver's space.c file before the driver will be able to use the new IRQ.
After completing the configuration of any devices connected to the SlimSCSI 1460 adapter, you must also do the following:
1. Edit the /etc/conf/pack.d/smad/space.c file.
2. Locate the following line:
  
  aha_change smad_irq[SCSI_NSMAD];
  and modify it so it looks like:
  
  aha_change smad_irq[SCSI_NSMAD] = {1, <irqnum>};
  where:
  
  1
  
  indicates that you are changing the IRQ
  
  <irqnum>
  
  the new IRQ setting that you specified
  
  For example, if you configured your SlimSCSI 1460 to use IRQ 5, you would modify the space.c file to read:
  
  aha_change smad_irq[SCSI_NSMAD] = {1, 5};
3. After modifying the space.c file, you must relink and reboot the kernel so that your changes take effect:
  
  # /etc/conf/bin/link_unix -y
  # shutdown
