This is my old trusty laptop. It's an old model, I put this page up only because the original 6200MX page is no longer maintained, and you need to know one critical detail about X to get it to work right.
Win98 and RedHat 7.1 install easily on the machine, but it's really too slow for them. I'm back with RedHat 6.2 and still happy.

|Status with RedHat 6.2 (With 2.2.14-5.0 Kernel)|
|Display||Works||Easy||Select monitor type "Generic Laptop 1024x768". See tricks section. May also be supported by XiGraphics|
|2 Button glidepad||Works||Automatic||Would be nicer if it had a third button.|
|USB||Available||Automatic||Under Kernel 2.4.4, plug in a CardBus USB adapter and it will just work. See linux-usb.org for compatible cards.|
|Floppy CD Serial Parallel Keyboard VGA||Works||Automatic||Belkin's PS/2 Y cable allows a mouse and keyboard to plug in at the same time.|
|Sound||Works||Automatic||I use soundblaster emulation. May also be supported by 4Front Technolgies Drivers.|
|IrDA Infrared||?||?||Works under Windows. Never found a use for it other than hotsyncing Palm Pilots.|
|Power: Screen Saver||Mostly Works||Automatic||Somtimes you must press the lid switch to get the display back.|
|Power: Battery Status||Works||Automatic|
|Power: Suspend to ram||Often fails||Automatic||Just press the sleep button, or use "apm -s". About 20% of the time the machine reboots when you start it back up.|
|Power: Power off||Works||Automatic|
|Vendor specifcations||NEC Support|
|Hard drive||Standard 12mm height drive. Vendor-specific bracket. Possible to swap drives, just requires a lot of tiny screws.|
|RAM||Under keyboard, akward to access.|
|CPU Fan||Only runs on very hot days. Quiet usually.|
|Versions||Extact model tested: PC-6250-B1854-R. BIOS as shipped & tested: 0020 03/25/97 . Hard Drive: Not original|
|Strengths||Feature rich at the time. Nice screen. Runs Linux well.|
|Notes||Did I mention it's heavy?

The XFree86 video driver changed a few years ago, reducing the range of allowed video frequencies for this machine's chipset. Add the following lines to undo the change. Without these lines, you won't get full resolution:
Section "Device" Option "fast_dram" # Needed to prevent screen glitches Option "hw_cursor" # Set to "sw_cursor" in case of problems DacSpeed 65.00 # Override server's idea of what is safe # to allow 1024x768 at 16 bits per pixel EndSection
For reference, here are working configuration files for the machine:
To allow the hard disk to spin down more often, make the following changes to RedHat's configuration
