Something I've been messing with. Started out with aragons 4.2 SMP. Recompiled kernel for RT. It uses the pup_420.sfs from aragon's puplet with updated modules. As far as I know all the apps are patched.
This probaly is only of interest to those wanting to run audio applications with minimal latency. Rosegarden, Ardour, Reaper. Download at: www.agitprop666.com/PuppyLinux2.html
Big thanks to aragon and tempestuous for setting me straight on some technical issues.

Hi maggotspawn,

I downloaded Puppy 4.2 SMP-RT, the md5sum is OK, but it won't boot. I get the message:

ISOLINUX 3.63 2008-04-10 isolinux: Image checksum error, sorry...
Boot failed: press a key to retry...

I tried burning the Puppy 4.2 SMP-RT .iso image to good-quality Fujifilm CD-R's twice, using PBurn. Same error on both. The combination of PBurn and these Fujifilm CD-R's has proven reliable, so my initial guess is that the problem is with the .iso image.

Your DAW-PUP version does boot OK; I'm posting from it now. However, dhcp doesn't work. Network Setup wizard says it worked, but a check reveals it has assigned that usual 169.n.n.n dud address. One of the few dhcpd's I've found in any Puppy/Puplet that does work, at least on my machine, is in 2.16CE.

DAW-PUP's kernel has slightly worse benchmark performance as shown by hardinfo, versus Puppy 4.1 outfitted with an SMP kernel. Not sure if this is because of the RT patches or the newer kernel. However, despite its slightly worse benchmark scores, the subjective overall snappiness of DAW-PUP is better than Puppy 4.1 with an SMP kernel. FirePup runs nice and fast, what few applications I've tried open with pleasing speed, and PFind across my half-terabyte of disk space (on 7 disks divided into 13 partitions) happens faster than on any other Puplet I've tried.

DAW-PUP may become my regular Puppy, at least until I finish constructing one of my own that I'm satisfied with.. Good work!

Doh, I'll have to look into that iso error. Thanks for checking them out. Smile

Got it sorted. I could have sworn I booted with the CD, but I guess I didn't. Was using it to remaster DAW-PUP. Had to remaster RT-SMP. Fixed version up in about 10 minutes. Thanks for catching that. Embarassed

O.K. fixed version is up. Thanks again, Sit Heel Speak.
Woof Woof! Smile

Sit Heel Speak caught an error on my part with the kernel, recompiling now. Will be a day or so before the real RT version is up. Patched the kernel but failed to enable RT. Yes, I'm a newb.

Fixed version is up. I'll try to get the kernel source up tommorow.
Hardinfo says #1 SMP PREEMPT RT under operating system, so that's a good sign.

Here's the .config
I googled this: http://rt.wiki.kernel.org/index.php/Frequently_Asked_Questions
All kernel config settings seem to be good now.
