Then - why not combine them (like it was in the past with the smp and non-smp), why there is a need of -default and -pae? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

What is the rule which YaST uses to decide which one to install on a new system? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

It is up to the motherboard chipset whether to make use of this tho. ie, a 440BX would not use it, but a 440GX could use it. Only the x86-64 chips have the ability to use the NX bit since it uses the 63rd bit, so why would you even make use of it on a 32bit chip? If YaST is just looking for PAE to enable something like NX/XD, then that's silly. I believe that Svetoslav was refering to older machines like my Thinkpad with the P3/500. While the chip may support PAE: flags : fpu vme de pse tsc msr pae mce cx8 sep mtrr pge mca cmov pat pse36 mmx fxsr sse up and the corresponding pse36, PAE is dependant upon the northbridge supporting. Bottom line, is this something that will slow down a non PAE usable system? Is the code able to be removed, like the SMP alternatives are removed saving 18k on my system?

That's the only series of chips that were 32bit that had it(None of the 32bit Athlons had it, it wasn't added until the Athlon64, and it was only after that that intel added it and only on 64bit P4's until the Dothan P-M). And, all things considering, I remember hearing that some people thought that the Pentium M/Core chips were actually 64bit, but that it was diabled, so that would still say that it's a mostly 64bit implementation, and useless for the 99% of 32bit x86 chips out there. Anyway, since it's only 2 small series of 32bit chips, it still begs to ask if having this enabled takes away anything or not. The PAE was added to the PPro and newer Intel chips. AMD didn't add PAE until the Athlon IIRC. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
