    • Composite Out is set in BIOS to disable/PAL/NTSC. Tested and works

  1. The "5" key can not be pressed. But it pressed it selves from time to time. - annoying. Have tried to clean the key without opening the machine. Fixed by remapping "5" to "nothing" by using Ansi.sys / nansi.sys (Freedos 1.2) and this in my autoexec.bat:

    • PROMPT $e[96;"5"p$e["5";0;79p$p$g

This remapps the "5" key to END, and the remapps " ' " to "5". So now when the 5 keys sticks it only sends an END og line command. This remapping only works in DOS.

IBM Thinkpad 390 - 1998

  • Pentium II Mobile 233Mhz, 160MB RAM, 3.2 GB HDD

    • Norton SI reports this machine at 584 x relative speed to IBM PC

    • AIDA report Sound Blaster Pro (DSP 3.01) 220H, IRQ 5 and DMA 1, NeoMagic NM2200, AdLib and Windows Sound System (530h). NSSI report MIDI port on 330h. Address, IRQ and DMA can be changed in BIOS

  • NeoMagic MagicMedia 256AV (NM2200) - 2.5 MB VRAM

    • SVGA (800x600) in 24bit.

  • Has D-Link G650+. But sadly this card does not support WPA2 in Windows 98SE

  • Have changed the CMOS battery. CR1220 - under a lid at the bottom.

  • After upgrading BIOS.The SAVE2DSK.BIN hibernation file did no longer work. I fixed this by creating a partition that was slightly larger then i had RAM. In my case i reduced the size (Partition Magic 6.0) of my partition so that i had 175MB free. When i then started PHDISK /C /P it created a partition in the empty space and formated it. After this the RED warning at boot, was gone.


  1. Considering a larger harddrive (CF, SD or IDE to MSata)

IBM Thinkpad 600e - 1998

  • Pentium II 400Mhz, 228MB RAM, 8.0 GB HDD

    • SVGA (1024x768) in 24bit.

    • Plays 320x200 games in full-screen - as mentioned this is a good DOS gaming machine

  1. Considering a larger harddrive (CF, SD or IDE to MSata)

IBM Thinkpad I Series Type 2611 - 1999

  • Pentium MMX 300 MHZ, 32MB RAM, 8GB CF - superfast

    • Norton SI report this machine at 1019 x relative to IBM PC

  • MS-DOS 6.22 - 4DOS 4.02 - no Windows because is used Compact Flash as Harddrive.

  • NeoMagic NM2160 MagicGraph 128XD - 2MB

    • 800x600

    • 320x200 scales to full screen

  • One USB port - working from DOS with DOSUSB

  • Yamaha OPL3-SAx - very good SB compatibility and real OPL3 chip

  • CD-ROM and 1.44MB Floppy

  • No fan noise

  • Very good DOS Gaming PC, full-screen gaming and full Adlib/SB Pro support.

PCMCIA NIC's

  • Have drivers to the Xircom - installed in both IBM Thinkpads

Dell XPS - 1997 - 1998 (est.)

  • Pentium II - 350 Mhz, 8 GB CF Card, 384 MB RAM

  • Windows 98SE

  • Sound Blaster Audigy 2 zs - SB0350.

  • Voodoo3 -2000 - 16MB AGP

  • 3,5" 1.44MB Floppy

  • CDR and DVD

  • YouTube video

  • Links: MPXPlay (Audio Player dos DOS) and Audigy12 - Patch for Audigy 2 cards using DOS drivers of Audigy 1

  • Note: The Audigy 2 zs WDM drivers for windows made the machine run slow and the Win9x games was unstable, and sound was laggy. But the DOS support was ok. With the VXD drivers windows games was much better, no lag, and Windows performed better. But no SB support in DOS. Uses DOS Drivers for Audigy 1 with patch to get support in Real DOS. - Works ok, but not perfect. Remember for Tick the MT32 box in SBEmixer.exe for Roland compatibility . Vogons.org has more. I am using the 8 MB Wavetable.

  • Note 2: Sometime midi does not work in DOS. Then it helps to start Doom2 to initialise the sound card. Also in some games like Tyran2K digitized sound does not work. I guess that the Audigy is not 100% compatible with SB Pro/16.
