Default BIOS update from Dell

I've done the Windows 7 Microsoft Updates for January. Now Dell is
offering a BIOS update for my computer model to deal with the Intel
security issues. I've never updated the BIOS before, and I wonder if
there are any problems I might encounter with this kind of update. The
only thing I see at the Dell website is to make sure I don't turn off
the computer or lose power during the update.

Also, Dell says to verify the checksum value of the download but doesn't
say how to do it. Is this something that will become obvious when
downloading? And if not, what do I need to do?

The details for the BIOS update of my model are at
http://www.dell.com/support/home/us/...driverId=FPCF7

Thank you,

I did it once without a problem and didn't check the check sum. They
make it easy. DO THIS WITH THE POWER SUPPLY CONNECTED and NOT on
battery.


KenW


Thank you, Ken. I always do updates with the computer connected to the
power supply. I figure the battery might help, though, if there's a
power glitch.

There are dozens of utilities to check hashes and checksums,
but if you don't want to install one just upload the BIOS file you
downloaded to Virustotal or Jotti and see if their checksums match the
ones on the download page.
If they match, and dozens of sirens don't go off, you should
be OK.
I believe this BIOS update just updates the backdoor. The old
version got hacked. But I've always been a little paranoid.

PS Yes, a BIOS update can brick your computer. Make sure you
are offline and that you are not running much in the background when
you do it.

If she's got 7-Zip installed she can use it as well. Simply rightclick
CRC SHA SHA--1.

"Updated to the latest CPU microcode to address CVE-2017-5715"

https://www.cve.mitre.org/cgi-bin/cv...name=2017-5715

The Spectre branch target buffer microcode amendment
is borked on a couple families of processors. If you know
for certain your processor is something else, then go right
ahead. Symptoms include reboots.

4th gen processor is Haswell

https://ark.intel.com/products/75128...up-to-3_70-GHz

Why this wouldn't be seen on other brands of computers, is
a mystery. Currently Lenovo is the only one showing a warning.
Intel should have released the same microcode to everyone.

*******

https://arstechnica.com/gadgets/2018...t-performance/

Spectre

IBRS ("indirect branch restricted speculation") protects the kernel
from branch prediction entries created by user mode applications;
STIBP ("single thread indirect branch predictors") prevents one
hyperthread on a core from using branch prediction entries
created by the other thread on the core;
IBPB ("indirect branch prediction barrier") provides a way to reset
the branch predictor and clear its state.

https://support.lenovo.com/us/en/solutions/len-18282

"Withdrawn Broadwell & Haswell CPU Microcode Update"

https://newsroom.intel.com/news/inte...reboot-issues/

*******

For MD5 and SHA1 checksums, Microsoft offers "fciv.exe" from their site.

And 7-ZIP has a right-click menu with SHA1 and SHA256.

http://www.7-zip.org/

MD5 is pretty fast to calculate. If you need to store local checksums
for an entire disk, computing MD5 ones is good. It detects unintentional
edits, like say a bad disk sector.

However, for Internet downloads, files hacked by hackers, it's possible
to modify the MD5 protected file so it gives the same MD5 as before.
Takes a minute with a P4 processor, to compute the right bytes to modify
to do that. Whereas SHA1 and especially SHA256, make it harder to edit
and corrupt files, without the end user running the checksum and getting a
completely different result.

You don't even need to compare the entire string of numbers.
Even if a single bit changes in the file, the string of numbers
will be entirely different. Just comparing a few of the digits
reduces your odds of accepting a counterfeit, by a wide margin.

And if you're lazy, *upload* the file to virustotal.com, as they
will list checksums for your file, for you. If Virustotal already
has the file, it won't upload your copy, and will just give info
about the file on their web page. There should be a page there
listing various checksums.

Dell says this:

MD5: e247faf09270731297491baf7bd18f48
SHA1: 9520fcb970f242c35a0151d0a9864ecae2ec20ea
SHA-256: e207e888445d2d34f6c42f8cb1fa3e2ea466efd66cd8b525d1 3df62cee350323

You can see the virustotal numbers match. The Details tab has two of
them, the main page has one of them.

https://www.virustotal.com/#/file/e2...0323/detection

Every motherboard BIOS update I've seen require you to create a special
boot media, either CD/DVD or USB flashdrive. You boot using that to do
the update. There's nothing else running AT ALL. Add-On cards, DVD
firmware etc. can be patched with the OS running but NOT the BIOS. The
OS depends upon the BIOS for functionality so it can't be "changed"
while being used. That'd create havoc and for sure a crash and likely a
bricked system.

Newer and some older systems can be flashed directly under windows, My
Asus X58 Sabertooth does and many others can do it. and I have done it
twice in the past, Progress you know.

Intel just came out with 'do not update microcode' warning, so I would
wait. This stuff has not settled down enough.

I did it to my dell also and it was seamless. Windows 8.1 would not run
on my 15r until I did the upgrade. I took weeks to find the bug,
minutes to do the flashing of the BIOS.

update the BIOS.

In days gone by, Windows flashing had a very poor reputation. They
did some stupid things, like downloading the file at the same
time they were flashing, then if the network connection broke,
the Flash would stop half-way, and the board would be bricked
on the next reboot.

Windows flashing is better today.

But consider this. What if your AV is active, and happens
to not like what the Windows flasher is doing ? What if
heuristic detection cuts in half-way through the flash
operation and quarantines the flasher. Or, say the flasher
and the AV get in a "fight" and the desktop stops
updating and freezes. These are the corner cases for
Windows flashing.

With MSDOS flashing, usually the Flash file was already present
(you staged it on C: and used a FAT32 capable version of
MSDOS floppy), and no AV would be running. That makes
things marginally safer.

The "USB stick" and "press a button to update BIOS" on my
newest machine, now that's a low-risk way of doing it. As
long as you have two USB sticks, and can insert the one
with the old BIOS, if you get in trouble :-)

I don't flash the BIOS all that much, because I don't
have a collection of BIOS Saviors to plug in. Only that
new machine, would it be worthwhile messing around. As
the Flasher is a separate chip and is autonomous from
the main CPU. You don't even need a CPU on that motherboard,
to run the push-button flasher.

Isn't yours a Haswell ?

Have you run the part number through ark.intel.com yet ?

I guess it depends on your trust in Dell, as to whether
this was "just the usual Lenovo issue", or it's a more
common situation that would be seen across all brands.

Because they won't tell us why it's rebooting, it's pretty
hard to guess which brands it affects.

A reboot because of a kernel panic should affect all
brands equally. But there could be other reasons it's
happening, and until they admit the cause, we won't know.

I'd want another Dell owner of the same model, to test
this update for me :-)

http://www.dell.com/support/home/us/...driverId=FPCF7

I did it once without a problem and didn't check the check sum. They
make it easy. DO THIS WITH THE POWER SUPPLY CONNECTED and NOT on
battery.

Thank you, Ken. I always do updates with the computer connected to the
power supply. I figure the battery might help, though, if there's a
power glitch.


Intel just came out with 'do not update microcode' warning, so I would
wait. This stuff has not settled down enough.

I did it to my dell also and it was seamless. Windows 8.1 would not run
on my 15r until I did the upgrade. I took weeks to find the bug,
minutes to do the flashing of the BIOS.


Hmmm, perhaps that'll be the road I MUST go down in order to install
Win7 on two older Dell XP's that reboot without installing anything when
trying to install Win7.

I've done the Windows 7 Microsoft Updates for January. Now Dell is
offering a BIOS update for my computer model to deal with the Intel
security issues. I've never updated the BIOS before, and I wonder if
there are any problems I might encounter with this kind of update.
The
only thing I see at the Dell website is to make sure I don't turn off
the computer or lose power during the update.

Also, Dell says to verify the checksum value of the download but
doesn't
say how to do it. Is this something that will become obvious when
downloading? And if not, what do I need to do?

Could you provide a link to the warning, Ken? I found this one:
https://www.cnbc.com/2018/01/11/inte...ome-chips.html

Is it what you're referring to?


Isn't yours a Haswell ?

Have you run the part number through ark.intel.com yet ?

I guess it depends on your trust in Dell, as to whether
this was "just the usual Lenovo issue", or it's a more
common situation that would be seen across all brands.

Because they won't tell us why it's rebooting, it's pretty
hard to guess which brands it affects.

A reboot because of a kernel panic should affect all
brands equally. But there could be other reasons it's
happening, and until they admit the cause, we won't know.

I'd want another Dell owner of the same model, to test
this update for me :-)

Paul



Thank you, Paul! I just ran it through, and it's listed under "Products
formerly Haswell"--which means, I guess, that I'd better hold off doing
the BIOS update for a while...
