This article was previously published under Q156357 SYMPTOMS
When you use an Adaptec 1542CP in a computer running Windows NT Server or
Workstation, Windows NT may pause during startup for up to 5 minutes. Event
Viewer may indicate Event Id 9 - "Device\SCSIportX did not respond within
the timeout period."
CAUSE
This error can be caused by a setting in the computer's BIOS.
The setting in question may be First available interrupt and contain a
numeric value. This setting determines what IRQs are available to the
computer's PCI devices. Other BIOS manufacturers use Reserved by ISA to
deny PCI devices access to those specified interrupts.
With Plug and Play disabled on the Adaptec 1542CP (which is the desired
setting when using this controller with Windows NT), the default interrupt
chosen by the controller is IRQ 10. If any PCI devices attempt to use this
IRQ (based on the BIOS setting for available interrupts), you may
experience the above symptoms.
RESOLUTION
Ensure that any available interrupts are NOT equal to the IRQ setting of
the Adaptec controller. If your BIOS uses the Reserved by ISA scheme of
interrupt control, then ensure the BIOS has reserved the Adaptec's IRQ
setting as Reserved by ISA.
