The Latitude CP and CPiD have the same exact motherboard but the bios determines whether or not you can have a Pentium or Pentium II. By flashing with the TR4 bios (a OEM bios) you can make it run in Dual mode. Simply install your Pentium II MMC-1 processor and boot up and then flash with the latest CPiD bios.
The CPxH/CPtV do not support Speedstep Pentium III processors. If one is installed, they will boot at the lowest speed the processor supports. To get around this, download the CPxJ bios floppy and run the bios with the /jabil switch. It will reprogram it with the CPxJ bios which DOES support speedstep.
The inspiron 3700 is the same way. Use the 3800 bios.
You can add pentium II support to an inspiron 3000 by swapping the 2 flash chips from an inspiron 3200 (purchase a dead board from ebay). Note: If you try to flash the 3200 bios into the 3000, it will kill it!.
The TR4 bios for the CP can be obtained from my website:

The other bioses can be obtained from the Dell website.
The Delltalk forums are another source for good info.

Also you can flash the latitude bios into the inspirons in many cases so that you can use the Docks with the PCI slots.

| The link provided earlier to the TR4 BIOS used to upgrade a Latitude CP to a CPi is no longer working. Can anyone provide the TR4 BIOS or a link to a download. It would really be appreciated. Thanks, Joe
