The T43 uses a pentium M, so yes. Just add: forcepae to the end of the kernel line in the menu.lst file.

@wizard Do I have to use the "-- forcepae" with my T43 when I finally get to (frugally) install Puppy?

@rcrsn51

For comparison:

Thinkpad T41 Pentium M, Bionic32
forcepae = boots
-- forcepae = (space before forcepae) boots
--forcepae = (no space before forcepae) boot fails

So what happens if you remove the -- argument? On the IBM T-42 if the -- argument is not added the forcepae is ignored. This 2004 laptop machine is only 32 bit, has no hard drive and no battery. Boots Tahr , Xenial and Bionic 32 bit variants but only with the -- forcepae argument and parameter. I ...

Are you sure that it's "--forcepae" WITHOUT a space and not "-- forcepae" WITH a space? The first one makes no sense as a kernel boot parameter.

-- forcepae WITH a space.

The only parameter that makes sense in Puppy is wizard's "forcepae".

In the previous setup, did you know for sure that the -- was required? Or did you just use it because someone suggested it?

Hello all: The forcepae command is used with the Pentium "M" series CPU to force compatibility (or bootability) with the Puppy OS. Dell Inspiron D800 and 8600 laptops use the Pentium "M" CPU. I used forcepae previously with a Dell 8600 laptop - allowed me to boot an otherwise un-bootable laptop. In ...

Hello, I have not attempted with this particular distro, but on my T41 with Banias core I have found success with appending "noexec=off forcepae" to kernel command line to disable NX bit and utilize the unflagged PAE support in both Devuan and Void Linux.
