IBM Thinkpad T42
Windows 9x
Instructions:

Intel 855PM:

Run either 'infinst_autol.exe' or 'infinst_enu.exe'. 

ATi Radeon 7500: 

Unpack WME 8.03 catalyst driver. To install display driver, open display properties in device manager, update driver, specify location, select driver from list, have disk, go to 9x INF folder in the unpacked WME 8.03 installer and finally pick either of the three RADEON 7500 SERIES entries from the giant driver list (scroll way down). If using Windows ME, you have to allow the uncertified driver to install, pick advanced option when offered and turn off the auto rejection. Install ATI Control Panel from the unpacked installer to finish. 

SoundMAX:

Run either 'd64z32us.exe' or 'sp24465.exe'. 

Intel PRO/10/100/1000 LAN Adapter:

Run 'tpet1u98.exe'.

Atheros/intel/thinkpad wireless
Thinkpad T42
Windows 9x
Instructions: 

Run '1qwc70ww.exe'. When installing the wireless driver (assuming you have the atheros/intel type wireless card), the driver and client should install fine. A possible issue may crop up when you restart Windows and the systray icon is supposed to appear. Sometimes it crashes, not sure why. When using Windows ME OEM, I tried installing KernelEx 4.5 Final and set the systray icon for the wireless client to Windows 98SE compatibility. That seemingly stopped the crashing. Windows 98SE may not require this. Just jotting this down just in case. 

The installer 'tpet1u98.exe' is there just in case the installer mentioned above doesn't work for you. 

TI Cardbus Controller:

Run 'ossa04ww.exe'.

Drivers not included:

Modem
SMBus
