This question has probably been a hundred times in this forum and yes I have read them all, so please read my post before I get answers like "search the forum first".

 

I have a IBM Thinkpad T41 Pentium M Centrino (yes the one without PAE mode). I can run the Vmware Image of 10.4.1 the floating around. But when I try to install any other version from Jas (I have tried - 10.4.6, 10.4.7) I get a PAE Error in VMware.

 

I have tried the paevm = "TRUE" setting and I have downgraded Vmware from 5.5 to 5.0. (those are the two most common suggestions in the threads here) - Still no luck.

 

Some say that PAE mode is necessary on a Vmware install but not on a native install. That doesn't make any sense to me though. Either the install dvd expects PAE or not, no matter if it's running natively or in Vmware.

 

If I look at the HCL of the different versions I see that 10.4.6 http://wiki.osx86project.org/wiki/index.ph....4.6#Processors Pentium M Banias "Works perfectly" and under Portables I see that the "IBM T41p 2373" works. And for 10.4.7 I see that "735A Dothan" (which should also be the same as Banias - both 400 Mhz Bus Centrino) works.

 

Now for my question: My CPU only supports SSE2 and no PAE. 10.4.1 runs under Vmware. Which version >10.4.1 can I install under Vmware? There has to be a version that is installable with a patched DVD. But which one should I use?

 

I've download quite some GB with no luck so far.

I'm greatful for all helpfull information.

Thanx ;-)

I'm sorry, but like I said in my first post, this doesn't make sense. Why would installing via DVD require PAE in VMWARE and not when installing natively?

It would seem to me that this is more a bug in VMware than the fact that PAE is really necessary.

 

Maybe another question: should the paevm setting cause VMware to emulate PAE or does this setting have no effect when the processor doesn't support PAE natively? If the latter is the case then this would be a bug in VMware, since a native install doesn't require PAE. Right?!

no. it's not a bug. It is a completely different environment. Physical Address Extension (PAE) is not needed natively but needed in VMware because you are still running within the limits of windows.
