Upgrading Agp Screen Controllers; Adding Pci Cards; Pci Bus Interrupts - Selecting Correct Pci Slot - Fujitsu Siemens Computers D1627 Technical Manual

Removing a memory module
1
► Push the clips on the right and left of the memory slot outward (1).
► Pull the memory module out of the memory slot (2).

Upgrading AGP screen controllers

Technical data:
The AGP slot supports the modes 4x/8x with 32 bits and 66 MHz. Only 1.5 V AGP graphics cards
are supported.
Some older 3.3 V AGP graphics cards are coded like 1.5 V AGP graphics cards. The
i
installation of such 3.3 V AGP graphics cards can cause serious damage to the
mainboard and the AGP graphics cards.

Adding PCI cards

Technical data:
32 bit / 33 MHz PCI slots
5 V and 3.3 V supply voltage
3.3 V auxiliary voltage

PCI bus interrupts - Selecting correct PCI slot

To achieve optimum stability, performance and compatibility, avoid the multiple use of
i
ISA IRQs or PCI IRQ Lines (IRQ sharing). Should IRQ sharing be unavoidable, then all
involved devices and their drivers must support IRQ sharing.
PCI IRQ Lines connect AGP slots, PCI slots and onboard components to the interrupt controller.
PCI IRQ Lines are permanently wired on the mainboard.
Which ISA IRQs are assigned to the PCI IRQ Lines is normally automatically specified by the BIOS
(see description in "BIOS Setup").
