Linux on a Maxdata Performance NB WX 440T

(Updated 17/06/2001)

This computer is a good ratio between price and performance.

It is composed of :

Device

Type

Works with

Processor

Intel pIII 650

Normal kernel

RAM

64 MB

Normal kernel

Screen

14.1'' 1024x768, active matrix

Xfree86 3.3 or 4.0

Graphic card

ATI 3D Rage LT Pro 4c42 8 MB-TV out

Xfree86 3.3 or 4.0. Chipset mach64-

The TV-out does not work.

3D accelerated : works automatically with Mandrake 7.2, but not very fast (Xfree 3.3).

Still not accelerated with Xfree 4.x

Mouse

Glide point 2 buttons

PS2- irq12

CDROM

Integretad Teac CD 224E (x24)

Normal IDE Atapi Ide1 - hdc irq15

Floppy

Integrated

Normal kernel - irq6

HD

Toshiba 6 Go

Normal IDE Ide 0 - hda irq14

Modem

Winmodem Lucent V90

Lucent Driver irq5 ttyS1 See Below

Sound Card

Crystal-Mic in-Headphones out

Alsa module cs46xx irq5

USB

1 port Intel 82371 ab/eb

Works with kernel 2.4 - irq 9 (UHCI module)

Parallel port

1 EPP port

Normal kernel irq7

PCMCIA

2 ports

Works fine with i82365 irq 10

Infra Red

1 port

Untested- irq3

Serial port

1 port

Normal kernel ttyS0 irq4

External screen

1 port

Works with/without integrated screen

External ps2 port

1 keyboard/mouse port

Works with a 3 button mouse, but impossible to make the glide-point work later. Necessary to reboot.

The keyboard must be plugged in before switching power on, but you can still use the embedded keyboard.



Making the modem work is now easy

You must get the driver at http://www.linmodems.org

The installation is very easy. You need to have the kernel source installed, activate ppp support, and then type « ./build_module » in the ltmodem archive (don't unzip the inner archive). Then « modprobe ltmodem ». It works with 2.2 and 2.4 kernels. It also works fine with french Minitel (V23 mode). The device name is /dev/ttyLT0.

Energy saving functions must be changed (in the BIOS). You must disable suspend mode and ask for the screen to get turned off when closing the screen.

You can use the Suspend mode only from a text console. If you want to use it from X without crashing the sytem, you must put in /etc/sysconfig/apmd :

CHANGEVT="7"

If you want your PCMCIA network still works after suspend mode, just write

NET_RESTART="no" in the same file.

If not, you must restart pcmcia (/etc/rc.d/init.d/pcmcia restart)

The mouse

Sometimes (rarely), the mouse gets crazy, but during a very short time only.

Hard disk and cdrom optimizations

hdparm -X66 -c1 -d1 -m16 -k1 /dev/hda

will accelerate your hard disk

hdparm -d1 /dev/hdc

will accelerate your cdrom

The frame buffer

It is not a good idea to use a frame buffer kernel. The text mode will work fine, but X will blink and will be very slow. In this case, X will work fine only if you use X frame buffer driver, which is slower than Mach 64 Driver.

You have perhaps seen the problem when installing the system if your distribution (Mandrake for instance) uses frame buffer during the installation. If you ask for testing your graphical configuration, it will blink. Just accept. It will work fine when starting again.

The boot

I had many trouble when trying to make LILO work on this laptop. I just managed to boot using GRUB.

Conclusions

This computer can be used with Linux. The only unsupported device is the TV-out (should work soon). The autonomy is short (about 1 hour). The sound card and the screen have been automagically configured by Linux Mandrake.
