A current list of the memory modules recommended for this mainboard is available on the Internet
at: www.fujitsu-siemens.com/support.
At least one memory module must be installed. Memory modules with different memory capacities
can be combined.
You may use only unbuffered 1.8 V memory modules without ECC.
!
DDR2-DIMM-memory modules must meet the PC2-3200U or PC2-4200U specification.
The installation/removal is described in the "Basic information on mainboard" manual.

PCI bus interrupts - Selecting correct PCI slot

Extensive information on this section is contained in the manual "Basic information on mainboard".
To achieve optimum stability, performance and compatibility, avoid the multiple use of ISA
i
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 "BIOS Setup" description).
