The intel video should work out of the box without any problems. The wireless network may need a driver for the broadcom but most likely again works for 99% of the things without it. Outside of that there is also elrepo with drivers and later kernels if needed. I have no idea about the status of Secure boot for Scientific Linux. If it is required for your projects then you may need to help SL team on it. Most enterprise laptops come with the ability to turn off secure boot because it breaks certain uses of Windows 7 and such. > Any information, on or off list, greatly would be appreciated. > > Yasha Karant > -- Stephen J Smoogen.
Re: Dell Latitude E6540
Is it X86-64 SL 6.5 or IA-32 SL 6.5 on your Dell E6520? What boot changes/hardware changes exist between the E6520 and E6540 (e.g., mandatory "secure boot")?

Thank you for your suggestion. Unfortunately, this Dell model that claims to be engineered and built to meet FIPS 201-certified smart card and fingerprint readers and RSA SecurID along with a MIL-STD-810G-tested chassis typically is not available in the local mass merchandiser computer laptop stores (Office Max, Staples, etc.). When my wife's laptop was stolen and we had to replace it out of our personal budget (her department had no funds to buy a replacement Faculty laptop because the university is "self-insured" for many situations, including that one), I did take a SL6x bootable DVD and found a machine for which SL6x would boot and that had sound, 802.11 WNIC, video card, DVD drive, pointing device, etc., fully supported by SL (not requiring proprietary MS Win drivers). The first several low priced laptops did *NOT* meet this criterion, but a Lenovo did. Unfortunately, consumer (low price) Lenovo is of poor mechanical quality (hinges/chassis already fatigue fractured), and unlike Dell or HP, Lenovo refuses to supply the service manual and full parts list, nor will it sell parts. Also, several stores would NOT let me do a DVD boot and run (not install) -- and thus i could not test which, if any, machines for sale would work. i suppose if we buy the Dell and it does not work we could attempt to return it, or I could be forced to switch to Ubuntu (not appealing).

Re: [SCIENTIFIC-LINUX-USERS] contents scientificlinux repo
There was a minor sync issue, it should be corrected now. Pat On 10/22/2014 08:02 AM, Werf, C.G. van der (Carel) wrote: LS.

When issuing command # yum update openssl It searches for openssl-0.9.8e-31.el5_11.x86_64 openssl-devel-0.9.8e-31.el5_11.x86_64 And for some days, this was ok, but now, it seems only these versions are in repo ftp://ftp.scientificlinux.org/linux/scientific/5x/x86_64/updates/security/ File:openssl-0.9.8e-27.el5_10.3.x86_64.rpm File:openssl-0.9.8e-27.el5_10.4.x86_64.rpm So, the update will fail, because 0.9.8e-31 versions are not available.

Have you considered burning a live CD or USB bootable image, visiting a computer store or someone in your IT group who has one, and taking a test drive with it with their permission? Laptop support for Linux can sometimes be tricky as vendors use slightly cheaper, newer chip sets that no one in th eLinux world has had a chance to test with, but I find that technique very useful to ensure basic bootability and X windows operation and peripheral operation.
