If There Is An Irq Problem - HP Vectra VEi7 Supplementary Manual

NOTE

If There Is an IRQ Problem

Problem
You have installed an accessory
board but it is not working.
You have installed a sound board
and you get a message telling you
that there is no IRQ (Interrupt
Request) available for the sound
board.
If there is still a problem
Plug and Play operating systems such as Windows 95 and Windows 98
should, in normal circumstances, be able to allocate IRQs according to
the hardware installed in the PC.
Solution
Check that:
1 The accessory board is correctly installed in the slot.
2 There are no bent connector pins.
3 You have installed the correct drivers (refer to the board
manufacturer's web site).
4 The relevant fields in the HP Setup program are correctly set.
5 The software installation steps have been followed correctly.
1 Check that you have followed the installation instructions provided
with the sound board.
2 Check if the new accessory board supports shared interrupts, and if
possible, implement a shared interrupt (refer to the accessory board
manufacturer for more information).
3 Remove the new accessory board.
For ISA Legacy accessory boards under Windows NT:
1 Restart the PC and press F2 when Press F2 to enter Setup is
displayed.
2 Go to the PnP/PCI ISA IRQ Resource Exclusion submenu of
the Advanced menu. By default, IRQ 5 is reserved for the
embedded audio device. Set another free IRQ to ISA (refer to page
75).
3 In the Main menu, set the Plug &Play O/S item to No.
4 Press the F10 key to save the changes and quit the Setup program.
5 Redo the Windows NT installation procedure for the sound board.
