Sony PCG-U3 and NetBSD

I’m not a serious collectionneur, but I like old micro notebooks. I have in my collection Compaq T1000, Fujitsu U810 and Sony PCG-U3. First two of them are bonded with the fully outdated software, available for Windows XP and Windows 7. Last one is a different case.


Sony PCG-U3 was selling on Japanese market only circa 2002. Initial prices was $1424 about. The ultra sub-notebook weighs just 820 grams. It was designed for Windows XP. It is a quite compact kind of UMPC, i.e. ultra mobile personal computer, equipped with

  • Processor Transmeta Crusoe 5800, 933Mhz
  • RAM 256MB DDR + additional 256MB memory module can be installed (*)
  • Video ATI Mobility Radeon-M 8MB (Dual View Capable)
  • Display TFT 6.4 (1024 x 768 internal, 1600 x 1200 external)
  • Hard Disk 20GB Ultra ATA
  • Audio Mega Bass with Theater sound and built in microphone
  • Keyboard 106/109 International Japanese keyboard
  • Mouse Jog Type: built in to keyboard
  • Ports/Slots (Built In) 2 x USB 1.0
  • 1 x iLink (1394 – 4 Pin) Firewire
  • 1 x LAN (RJ-45)
  • 1 x Biology U Port
  • 1 x Headphone Out (Mega Bass)
  • 1 x Microphone In
  • 1 x Magic Gate Memory Stick Slot
  • 1 x Type II PCMCIA
  • 1 x Jog Dial
  • 1 x Power Button
  • 1 x Display Port


So what to do with so outdated UMPC in 2024? There are three options: sell it on eBay, put it on a shelf and look at it, or try to use it with the most up-to-date software. The third way is a kind of challenge and I choose it.

PCG-U3 User manual (Japanese)

Hardware notes

Every CPU needs a good cooling, especially a CPU born around 2002. There is a good YouTube video on how to disassemble the younger brother of the PCG-U3, the PCG-U1, I removed the CPU cooling system and cleaned the CPU with isopropyl alcohol. Actually, it wasn’t a simple plastic strip. It was a type of strip that had been transformed into a dried, stone-like strip. I then applied new thermal grease.

A very rare CPU fan is used. It’s a Toshiba MCF-503PAM05 DC5V 150mA. It seems impossible to find this fan for sale on eBay, whether it’s new or old. It also seems that the fan can’t be removed from the heat sink without damage. So the only options are to clean it of dust and lubricate it. I used sewing machine oil.

This UMPC uses a Panasonic VL-1220(VL-1220/VCN can be used as well) 3V/7mAh CMOS/clock battery. Funny fact: I’ve installed a new VL-1220/VCN, but the internal clock still runs ahead at 4 hours.

Hard disk drive. By default, the PCG-U3 comes with a Toshiba MK2003GAH 20G IDE drive. I got it old and clicking so much that thoughts of incoming drive dead came into my mind. How to upgrade it? I’m skeptical about using CompactFlash cards with a special CF to IDE adapter, given the very limited number of write cycles CF cards have. SSD use seems to be possible in a way: mSATA drive -> mSATA to ZIF adapter -> ZIF to IDE cable, but I haven’t tested it. I think the best you can do is to upgrade the standard drive with a Toshiba MK6006GAH 60G IDE drive. And that is what I did.

Video. ATI Technologies Radeon Mobility M6 LY is the full name of the video card. It’s an old built-in AGP video card with 8M of RAM and rather questionable driver support. The Sony Windows XP (JP) support CD provides the Windows drivers for this video card. I had problems with the video card. More on this later.

DVD and CD-ROM. It appears that the PCG-U3 only supports external booting from Sony devices. I have successfully tested booting from a Sony PCGA-CRWD2 Firewire cable powered DVD & 20x CD-RW drive. I’m pretty sure other drives such as Firewire PCGA-DVRW1 and PCGA-DVD1 will also be able to provide external booting. Most likely Sony’s PC Card CD-ROM drive PCGA-CD51 is also external boot compatible. Important: I tested an average no-name USB DVD-ROM drive, and PCG-U3 wasn’t able to boot from it.

Memory Stick reader. It’s was detected by any of the tested OS. Fortunately only Windows provides full read/write support.

Display port. Requires a mini-VGA to VGA adapter to connect an external display. Apple adapters on eBay are compatible with the PCG-U3 display port.

Biology U Port. Perhaps it’s a wrong English translation from Japanese. Whatever it means in original, in PCG-U3, it’s a port to connect a Sony made Firewire device without external power supply with a special port cable. No OS drivers are required.

Jog mouse, built-in USB, built-in iee1394 adaptor, built-in network adapter, PCMCIA slot, sound card. All this stuff was working with any of the tested OS.

Reset button.

Special buttons

  • 1 – Zoom button. It changes screen resolution (*)
  • 3 – Jog dial or Back button (*). The jog dial can be used to perform some operations in each software, such as scrolling windows and selecting items. The BACK button is used when you want to return to the previous level while operating the jog dial, or when you want to delete characters while operating the ThumbPhrase software.
  • 4 – Standby button to reach the power-saving operation mode (*)
  • 6 – ThumbPhrase button (*) to use included “ThumbPhrase” software. It is software that allows you to enter text using simple keystrokes, just like on a mobile phone. You can enter data while holding the device with both hands (mobile grip style), making it easy to use outdoors. In addition, the ThumbPhrase” software uses a predictive conversion function to predict and display conversion candidates based on the characters entered. Predictive conversion has a learning function so that characters entered once are prioritized and displayed as conversion candidates the next time (*)

* – Windows only out-of-the box

Operating system

This UMPC was born to run Windows XP (JP). There are only 256M of RAM + possible installation of 256M extension card. Any Windows XP is out of support for years. From 202* years’ stand point any Windows XP has problems with security.

My target was a 32-bit OS, running on no-PAE CPU, still having community support, relatively fresh, providing maximum, for this UMPC hardware, support and 256M of RAM should be enough to run it.

Which operating system to choose? I did not want to go with Windows: it will either be outdated or slow. No desire to use any of the OS/2 family, even a fresh variant like ArcaOS. I just don’t like all that 32-bit DOS-mixing stuff. Kolibri OS? An OS written in assembler. It works. It is fast. But it can’t handle CPU frequency. I got constant hot air from the cooling fan when running Kolibri OS on PCG-U3. Also, Kolibri OS has no ssh client. That’s critical for me. Not all hardware is supported. The software available is very limited. So no KolibriOS. Haiku OS? It’s a new version of BeOS. The 32-bit version requires the PAE extension. So not a Haiku OS. So it should be an ether OS from the Linux or *BSD families.

Linux. There are only two variants: Gentoo (any release) or Debian 8. I do not have the patience to build an OS from scratch on such a slow CPU, so Gentoo is not my choice. Debian 8 is relatively new. I successfully installed it on the PCG-U3, but after that I couldn’t get the X server to boot properly. All I got was a blank screen in VESA mode. So Debian wasn’t selected.

BSD family. Which one? FreeBSD? The last one with no-PAE support was v. 12. The installation is quite complicated and requires the presence of a boot CD-ROM and a boot USB flash drive. After installation, the firewire adapter wasn’t detected. All binary ports have been removed from the FreeBSD repository as of 1 January 2024. So no FreeBSD. OpenBSD? It seems to me that 32-bit architecture support is sporadic in this project these days, and was only limited by the outdated v.4 version. NetBSD? Version 9.3 was released on 22 August 2022. It’s quite fresh. The upcoming version 10 promises to continue 32-bit support. Let’s give it a try.

Windows XP note

Sony Vaio PCG-U3 driver backup CD is still available for download from the Internet Archive site.

NetBSD 9.3 i386

PCG-U3 can run NetBSD 9.* and 10.* families and most of PCG-U3 hardware are supported. Installation is fairly straightforward, at least if you’re an intermediate UNIX user, i.e.

  • burn NetBSD bootable CD or DVD
  • boot from the bootable disk
  • follow the document

How it looks like

Screenshots are taken in 800×600 resolution. All whistles and bangles you see below are not out-of-the-box. It’s a deep customization.


The “Plug & Play O/S” option on the “Advanced” page must be set to “NO”. Otherwise the NetBSD “poweroff” command will cause the kernel to panic and reboot.

xorg.conf file

You need to create it manually if you don’t want to use VESA mode

Section "Device"
Identifier "Card0"
Driver "radeon" <<-- exactly this driver must be used
Option "BusType" "PCI"
Option "DPI" "96 x 96"

Next step is to replace default radeon driver file with the old one. A working example:
