Enabler displays following messages: "Detected PC Card 'Adaptec, Inc, APA-1460 SCSI Host Adapter' in Socket x:x:x", "Error: No supported SCSI adapters found."
Description: A card is not recognized by enabler. Socket is not powered up.
Reason: Adaptec SlimSCSI 1460 card supports very limited set of resources. Card Information Structure (CIS) allows to use only I/O address at base 0x140 or 0x340 and IRQ 9, 10, 11, 12 in ISA mode only (Level, not-sharable). If one of two I/O addresses is usually available the IRQ could be a problem on some of machines. On today computer the IRQ 12 is never available (used by PS/2 mouse). The IRQ 11 is commonly used by PCI devices. The IRQ 9 or 10 is available on most of the system, but not on all. E.g. BIOS of Toshiba Satellite 1625CDT uses IRQ 9 for USB, IRQ 10 for Rockwell modem and IRQ 11 for ATI Rage VGA. Since SlimSCSI 1460 Card declares that IRQs should be used in ISA mode only (i.e. IRQs are not shareable) Adaptec card will be never configured by CardWare on such PC. The only remedy is to get a BIOS update for such machine.
Solution: In order to make SlimSCSI work you will typically need to:
  1. Start enabler with /V+ switch and inspect output of used resources. Make sure that I/O range 0x340-0x35F is not in use. Also make sure that IRQ 9, 10, 11 or 12 are available.
  2. Start enabler with /CI:n switch where n - is non-used IRQ (9, 10, 11 or 12).
Notes: In rare situations it happens that the above setup is not working. It usually due to one of two reasons:
  1. Resource conflict. Please use any computer diagnostic program to check if the I/O range of 0x340-0x35F and IRQ 10 (9, 11, 12) are in use by other hardware. If they are and you cannot free them, there is no way to make 1460 work due to extremely limited set of resources supported by that card.
  2. Improper setup of PC Card adapter by BIOS. If you are sure that I/O range of 0x340-0x35F on your computer is free and IRQ 10 (9, 11, 12) are not in use, you may have have to adjust interrupt mode by adding some switches to Enabler command line. Please refer to the article Problems with PC Card 16 interrupt and initialization of PC Card Controller for details.

Please also notice that despite the fact that Adaptec documentation claims that I/O range 0x140 is supported, we were never able to use it. The I/O range 0x340 works fine.
