4. 6. Hotplug (Modem, Ethernet, Scanner) 17

mod ATI Radeon

At boot time, somebody or something tries to access DRI but does not howtodoso. This produces the error

message:

DRI module error message:

[date] [machine] modprobe: Can’t locate module−char−major−226

To help out, we create the ﬁle /etc/modutils/dri and update /etc/modules.conf.

/etc/modules/dri:

alias char−major−226 radeon # DRI

Updating /etc/modules.conf:

4. 5. IEEE1394 Firewire(Disk)

According to /proc/pci, the the IEEE1394 Firewire Controller is a 1180:0552 (Ricoh Co Ltd) (rev 0),which is of

the OHCI-1394 type. Tomakeuse of our external LaCie Firewire Hard Disk, we have toconﬁgure for IEEE

1394, OHCI 1394, SBP-2 as well as SCSI disk support.

Kernel conﬁguration for IEEE1394 FireWire:

—— IEEE1394 (FireWire) Support ——

mod IEEE 1394 (FireWire) support

mod OHCI−1394 support

mod SBP−2 support (Harddisks etc.)

mod Raw IEEE 1394 I/O support

Kernel conﬁguration for IEEE1394 FireWiredisks:

—— SCSI Support ——

yes SCSI support

mod SCSI disk support

2Maximum number of SCSI disks that can be loaded as modules

yes Enable extra checks in new queuing code

The actual conﬁguration necessary to access the external hard disk is described in a different section.

4. 6. Hotplug (Modem, Ethernet, Scanner)

The CardBus (PCMCIA) controllers are Ricoh RL5c476 II (rev 168) devices, which are supported by the stan-

dard kernel. Since the standard kernel supports driverhotplugging, we don’thav e to install anyspecial PCMCIA

drivers anylonger.All we have todo, is to install the packages providing the necessary infrastructure and then

conﬁgure the kernel for our cards, i.e. the 3COM 3CCM156 Modem PC-Card, 3COM 3CCE589EC Ethernet

PC-Card,and the Adaptec APA1480A CardBus-Card.

Debian packages for Hotplug (PCMCIA) support:

pcmcia−cs

hotplug

usbutils

Kernel conﬁguration for hotplug support (Modem, Ethernet, Scanner):

—— General Setup ——

yes Networking support

yes Support for hot−pluggable devices

—— PCMCIA/Cardbus support ——

yes PCMCIA/Cardbus support
