The other

green LED "T"

may flicker sometimes (it always lights up during

BUS-Master DMA transfers; the brighter it lights, the more DMAs).

The

yellow LEDs

indicate accesses to the devices. They also may flicker occa-

sionally as the ICP Controller scans the I/O channels for existing devices.

The ICP boot message appears. In the following example, a GDT8523RZ Controller has been
detected in PCI slot 3, and it has 32MB of RAM.

The single messages have the following meaning:

BIOS located at 0x000E0000 - 0x000E1FFF

Unlike ISA or EISA computers where the BIOS address of a peripheral expansion card is set
manually (ISA, jumpers) or with the help of a configuration file (EISA, cfg file) and the ad-
dress space is determined by the user, the PCI system-BIOS automatically maps the BIOS
of a PCI compatible peripheral expansion card to a memory address. At each cold or warm
boot, it determines which address space to assign to the BIOS of an expansion card. The
message shown above reports the physical address occupied by the GDT BIOS.

[PCI 0/3]

PCI

device, bus system

, slot

. The PCI 2.x specification allows several PCI bus systems to

be present in one PCI computer. All ICP Controllers have been designed to support multi-
ple PCI bus system computers. The slot number indicated in the message above does not
refer to the 3rd PCI slot, but indicates that the ICP Controller is plugged into a slot which is
the third one the PCI chipset of the PCI computer can access. To determine which physical
PCI slot this corresponds to, consult the system manual of your PCI computer.

DPMEM at 0x000D0000 - 0x000D3FFF INTA = IRQ10

DPMEM

stands for

ual

orted

MEM

ory. The ICP Controller needs this address space of the

PCI Computer for the command communication. As with the ICP Controller BIOS, this
mapping, is also automatically carried out by the PCI system-BIOS. This information is es-
sential when installing Expanded Memory Managers under DOS and Windows. The GDT
DPMEM address space has to be excluded from the control of such a manager. (For more
details, see chapter D of this manual). Furthermore, this messages tells us that the PCI

INT

of the ICP Controller has been assigned to the system

IRQ10

. This assignment, is also car-

ried out automatically if the PCI system-BIOS is 100% PCI 2.X compatible.

GDT8523RZ -- HWL0 -- 32 MB SDRAM / ECC - 2048kB Flash-RAM

GDT8523RZ -- HWL0

stands for the type of ICP Controller found by the GDT BIOS. HWL

means Hardware level.

32 MB SDRAM /ECC

indicates that the installed DIMM is a 32MB ECC
