BionicPup won’t run an HP 2740p’s WiFi either

Just discovered that BionicPup (64-bit) (Puppy 8.0) won’t run the HP Elitebook 2740p’s wifi either. modprobe’ing iwlwifi then iwldvm automatically brings in cfg80211 and mac80211 but, no WiFi shows in the network managers. Fedora 29 and Windows 10 can run WiFi on this computer.

EasyOS 1.0.14 will not read ExFAT created by Windows 10

Like the subject line says, EasyOS will not see/read a USB stick which was formatted ExFAT by Windows 10. Fedora 29 can.

Wireless not working in EasyOS 1.0.14

Nope, no wifi in EasyOS 1.0.14 either. The stack
iwlwifi
iwldvm
cfg80211
mac80211

which works in Fedora 29 and Quirky Unicorn, does not work in EasyOS 1.0.14 on this HP Elitebook 2740p.

*edited 2740p not 2940p

Wireless not working in EasyOS 0.9.4

Downloading 1.0.14 now, will try it. This is on a vintage-2010 HP EliteBook 2740p. On Quirky and Fedora 29 the wireless modules are iwlwifi, iwldvm, mac80211, cfg80211. Modprobe'ing these four into EasyOS 0.9.4, no wifi shows in the network setup app. Will try 1.0.14 presently and report back.

(***edited: I should've studied the readme that comes with the source to iucode-tool before I tried fixing this.***) I've deleted my wild guesses and rants which were formerly here.

Re: Intel/Linux 20% slowdown

Thank you, Keisha!...Well done, Sherlock :) Urk. Not so fast. More like "No cigar, Clouseau..." Merely installing the intel-ucode .deb alone, evidently doesn't get the microcode actually installed. I'm studying the article https://www.pcsuggest.com/update-cpu-microcode-in-linux/ right now...

The title of this thread, "It's official: Intel to only patch past 5 yrs chips ;-(" is mistaken, since Intel does seem to be making a good-faith effort to supply the necessary microcode to defend against Spectre, for processors older than five years. The Intel microcode update page ( https...

Re: Intel/Linux 20% slowdown

Does anyone know of a list or spreadsheet that shows machine make, model, year manufactured, CPU make and model, Kernels effected and other relevant data? A composite list? Thank you in advance. AMD and Intel issued more-or-less simultaneous public releases today at about 3PM New York time. I happe...

I have an AMD machine (A-series) that I can use, but for best security on that I'd have to shift away from my favourite Puppy distro to something with rolling updates to ensure all applications are Spectre-proofed, which would be a shame. Or wait for a Puppy to appear with an appropriately patched ...

Short version: start Linux with pti=on in the kernel line of the bootloader. I don't see how that will help unless you're running a version of Linux with the patched kernel, which presumably almost none of us are. I can find no mention of the "pti" switch prior to these events, so I'd exp...

Well, I'll try to answer this; bear in mind, I am not an expert... My reading of all the news leads me to believe the short answer depends on whether you have an AMD or Intel CPU.

Re: the Intel pti bug slowdown --impact on hardinfo

Another random thought, devices are getting smaller and smaller and have less surface area to disapate heat. This slows down CPUs. If this slows down the CPU enough then maybe it will run as slow as the rest of the components. The above benchmarks were run with Fedora's default Powersave governor. ...

I use grub2 and it's been a long time since I used extlinux, but I imagine you can.

the Intel pti bug slowdown --impact on hardinfo

Hello all, long time no see. According to https://www.postgresql.org/message-id/20180102222354.qikjmf7dvnjgbkxe@alap3.anarazel.de you can do what the patchset will do by setting pti=on (pti = page table isolation) in the kernel line of the grub bootloader. At work I use a dual xeon e5-2696 v3, runni...
