Video Card

The video card is a Cirrus Logic (www.cirrus.com) CL-GD7548 1MB. It is supported directly by the SuperVGA server (XF86_SVGA) for XFree86 release 3.3.2 To configure the video card you have to add the following “Chipset” entries to your /etc/XF86Config file.

Section "Device"
     Chipset "clgd7548"
EndSection

In order to work with the LCD display instead of an external monitor, you have to use this specific “modeline”.

Section "Monitor"
	ModelName   "Unknown"
	HorizSync   31-40
	VertRefresh 55-70
	ModeLine "800x600" 39.99 800  840  968  1004  600  601  605  632 +hsync +vsync
EndSection

In case of problem add: Options no_bitblt to the display section.

Notes:

When you leave X-Window, the screen remain blank ! To avoid such problem you should install the “SVGATextMode” package and invoke “stm” at the end of the /usr/X11R6/bin/startx script. This will make your screen re-appear however you need to press Fn + F4 once to make it work better.

Soundcard

Soundcard, in order to work, need to be configured with the “isapnp” linux utility.

This because it is an ESS1868 Plug and Pray If you have it installed then the file /etc/isapnp.conf is created. Please remove any comment lines to enable the settings as below.

This is MY isapnp.conf file:

(READPORT 0x0203)
(ISOLATE PRESERVE)
(IDENTIFY *)
   (CONFIGURE ESS1868/-1 (LD 0
))
(CONFIGURE ESS1868/-1 (LD 1
  (DMA 0 (CHANNEL 1))
  (INT 0 (IRQ 5 (MODE +E)))
  (IO 0 (BASE 0x0220))
  (IO 1 (BASE 0x0388))
  (IO 2 (BASE 0x0330))
  (ACT Y)
))

PCMCIA

PCMCIA works very well with Linux PCMCIA Card Services 2.9.6. The recognized controller is a Cirrus Logic compatible CL-PD6729. I have no problem using a network card 3Com 3C589D and a generic FAX/MODEM at 28.800 bps

This is my /etc/pcmcia.conf:

PCMCIA=yes
PCIC=i82365
PCIC_OPTS=
CORE_OPTS=

NETWORK ADAPTER

I only use a 3Com 589 Etherlink III adapter, and it works flawlessly. I installed the pcmcia package, and had to do no modifications at all. The card is detected and initialised at boot time or when inserted, and the card is correctly disabled when removed.

Serial Ports and IrDA

The /dev/ttyS0 is for the onboard serial port. The IrDA should be seen as /dev/ttyS1 but i never tested it. When i connect my PCMCIA FAX/MODEM it is “seen” as /dev/ttyS2.

CD-ROM

No problem, it is ATAPI Compatible and is “seen” as /dev/hdb It should be installed into the Floppy slot and connect the floppy onto the parallel port, you should halt your system to do that.

Touchpad

Again no problem, work as a normal PS/2 mouse.

Advanced Power Management (APM)

No problem. If you install the “apmd” package you can use “apm & suspend” to “freeze” your PC.
