|CardWare with Adaptec SlimSCSI 1460 card|
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). 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.
In order to make SlimSCSI work you will typically need to:
;I/O=0x140,0x20,E,10 ; Normally not used I/O=0x340,0x20,E,10 ... IRQ=9,E ; Check if IRQ is available IRQ=10,E ; Check if IRQ is available IRQ=11,D ; Use IRQ 11 with dynamic share only since it's PCI IRQ
It's very important that IRQ used by CardWare is free and match to the IRQ that you specify in /Q parameter of ASPI2DOS.SYS. You may check which IRQ is used by CardWare running DOSCARD /D. If IRQ selected by CardWare doesn't work, you may exclude it from cardware.ini by placing XIRQ record instead of IRQ record. E.g. XIRQ=10,E. After system reboots, check with DOSCARD which IRQ is used now and specify the same in /Q parameter of ASPI2DOS.SYS.
If you are trying to use SlimSCSI with IOMEGA JAZ device we recommend that you are using IOMEGA GUEST.EXE application rather then stack of ASPI drivers. It gives more compact image on the floppy.
In rare situations it happens that the above setup is not working. It usually due to one of two reasons:
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.
