Hello LenThank you for your help.In at least 3 computers I have come across, that has this option grayed out. As shown in pic1 of that link you supplied. So it is not accessible. Every link I came across, basicly had the same solution you described. There for those three computers can not have a true format done. All three have corrupted hinden partions. Putting a new hard drive will not help either. New mother boards would help.Cheers Abby Sent from my Samsung device -------- Original message -------- From: Lennart Sorensen <lsorense(a)csclub.uwaterloo.ca> Date: 08-11-2015 10:25 (GMT-05:00) To: GTALUG Talk <talk(a)gtalug.org> Subject: Re: [GTALUG] UEFI bios/firmware On Tue, Aug 11, 2015 at 12:39:02AM +0200, Abby Bassie-Cripps wrote: > <html><head></head><body><div style="font-family: Verdana;font-size: 12.0px;"><div> > <div>Hello Len</div> > > <div> </div> > > <div>That was very informative, thank you.</div> > > <div> </div> > > <div>For an update, the main computer is question is a toshiba satellite with win 8.1.

Other than the simple out dated method that we all know about?</div> Well from what I can find the process is: When you see Toshiba logo, hit F2, then you should be in the UEFI (BIOS) settings. Under security tab there should be an option for 'secure boot' which you want to set to disabled. If you want to keep windows working, that should be all you change, and then you should be able to install linux as long as the distribution is new enough to support UEFI booting. If you don't want to keep windows and you want to use an older style distribution that does not do UEFI booting, then you have to also find the "CSM boot" setting (under advanced/system settings) and turn that on. That will break booting windows 8.1 on the machine though. I would personally stick with UEFI booting these days. https://aps2.toshiba-tro.de/kb0/TSB2B03F30002R01.htm -- Len Sorensen --- Talk Mailing List talk(a)gtalug.org http://gtalug.org/mailman/listinfo/talk

question -- how to boot from USB with multiple ISOs?
by William Park 01 Oct '15

01 Oct '15

Hi all, Right now, I'm carrying around 2 USB sticks, - one 32GB -- it boots Linux and contains about 10 bootable ISOs. - one 8GB -- to 'dd' the real ISO that I want to boot. It's 2-step process, and it's ok. But, I would like to reduce it to 1-step. How can I boot those multiple ISOs directly from one USB stick? Eg. if you want to boot Fedora/Ubuntu/Clonezilla, what do you do? I guess you can carry around 3x8GB USB sticks, http://www.canadacomputers.com/product_info.php?cPath=11_180_632&item_id=07… but 1x32GB USB stick, http://www.canadacomputers.com/product_info.php?cPath=11_180_181&item_id=05… is better, I think. -- William

Using (Tomato) Linux (Router) as Web Proxy Server.
by Peter Renzland 23 Sep '15

23 Sep '15

Request for help: Using (Tomato) Linux (Router) as Web Proxy Server. I remotely manage several Tomato networks. I would like to connect to the ISP's Usage Data web page, from the remote network, to check the remote network's data usage. I'd also like to run the ISP-specific (web browser) speed test from the remote network, to check the remote network's data rates. These seem like very ordinary, simple things to want to do. I'd like to find someone who has actually done these things, and who can help me do them. (I have found dozens of "how-to" web pages that don't work for me. But I have not found anyone who has said "I do this all the time, and here is how I do it". Instead, I have found many people who have said "I have never done this, and I won't try to do it myself it, but you should try this ....") Being able to do a web search on "my IP" and get the remote (proxy) host's IP address is really all need. So, if there is someone who actually has done this, please help! Thank you very much.

Hello All, is there a TeamViewer-like solution for ssh only devices? I have a few remote Linux/FreeBSD systems that I take care of, but I don't want to fire up VPNs or expose port 22 to the internet.

OT: Inexpensive laptop for Minecraft?
by Matt Price 15 Sep '15

15 Sep '15

Hello everyone! Thought I'd tap the collective brain. I'm looking for a relatively inexpensive laptop for my son, who mostly just plays minecraft (and occasionally needs the computer for school work, using google docs & a browser). Any suggestions of models, or places to buy? I'm looking for something pretty inexpensive, but with dedicated graphics that will allow him to play minecraft comfortably for the next year or so at least. Thank you! m

GTA Monitor Repairs
by Clifford Ilkay 14 Sep '15

14 Sep '15

Hello, I purchased a new 4k Wasabi Mango UHD420 monitor on eBay from Korea in May and now it needs service. It's not feasible to ship this 42" monster back to Korea for service. I have a SquareTrade warranty that will cover local repairs. Does anyone know of any repair shops in the GTA or someone who will come out to my place to fix this thing? If you're curious how this works with Linux, I had to upgrade my video card to a GeForce 960. I bought an ASUS because that's the only manufacturer that has local RMA, apparently. I had to install the binary driver. It didn't work with Fedora 20. I didn't waste any time troubleshooting it and just did a clean install of Fedora 21. I keep /home on a separate partition so I was back in business in under 20 minutes. All I had to do to make the fonts look right in KDE was to check "Force fonts DPI" and set it to 105 in System Settings>>Fonts. When this monitor works, it's beautiful. Unfortunately, it appears the electronics in this thing are half-baked. Within a week, the screen started losing sync on the right side and eventually died on the right side. It's an interesting failure mode because this is one panel, not two. I offered to replace the defective parts if the eBay vendor shipped them to me. They were only too happy to do that because under the terms of the sale, they would have had to pay shipping both ways, which I'm guessing for something this size would easily be $200. They sent me a new video board and I replaced it in about half an hour. From the time the monitor failed to the time it was running again was just under two weeks. The vendor seems to answer no more than one email every 24 to 48 hours. That board worked perfectly until July when I started seeing "tearing" all over the screen as it momentarily lost sync. I reported this to the vendor and they wanted a video of it happening to do anything about it. It wasn't happening in a predictable or frequently enough that I bothered. Last week, the "tearing" got worse and there was a new symptom. The brightness would fluctuate on its own. (I had turned off adaptive brightness because it didn't work well for me.) This progressed to the screen going completely dark with a regular popping noise coming from the internal speakers. If I turn off the monitor and let it cool down, it will turn on again and the loss of sync and eventually going black cycle will be repeated. -- Regards, Clifford Ilkay +1 647-778-8696

QEMU and GDB debugging a kernel module
by Aruna Hewapathirane 10 Sep '15

10 Sep '15

Hi everyone, I am able to run qemu and get the *.iso files to boot fine. The qemu image works as well. But for the life of me I simply cannot get gdb to trigger when I set a break point in my kernel module ? I had trouble on my Debian 64bit, gdb complained saying "remote g packet too long" so I patched the remote.c file in gdb and things seemed okay but I am not sure if this did not introduce more bugs. And qemu wouldn't drop me to a shell but hung saying cannot find /bin/init.. So, to double check I ran Ubuntu-MATE 32 bit and all seemed well. But it still will not trigger gdb on my kernel module's break point. Has anyone ever used qemu and gdb ? If so has anyone successfully debugged a module ? I would be very thankful if someone can show me the 'specific' steps to follow to get this going. Documentation in the public domain is sparse and am yet to find something that gives a detailed breakdown of the steps and process. Thank's - Aruna
