|Do you work in the oil or natural gas industry, or are you doing a job related to that by any chance?|
I live in Alberta in Canada - there's a lot of people working here in those or in occupations that supply or depend on that.
Alberta, Saskatchewan, and Newfoundland, in particular, all have a lot of that.
"I didn't know that Phoenix was a brand. I thought it was a kind of BIOS or something"
It's a brand of bios software. There are only a few - Phoenix , Award, and AMI are the most common ones. Phoenix merged with Award some years back. You often see one of those brands on the screen while booting, often along with a specific bios version number. Phoenix bios versions are commonly used on mboards made by Intel, including OEM versions of their mboards that are often supplied to brand name system builders. Most if not all other mboard makers use an Award or an AMI bios version.
Each particular overall bios version of a brand is a generic "software framework" - that "software framework" is modified by, or by somone for, the maker of the mboard, or the brand name system builder, to suit the particular mboard model's main chipset chips the and I/O chip, sometimes other chips as well, so that the bios can properly interface (~ communicate) between the hardware and the operating system. That's the specific bios version for your mboard. When you flash the bios for a model, you're modifying the specific bios version, not the overall bios version, so it's very important to make sure you flash with a bios version for your specfic model, and often, the specific Revision or Version of the mboard model.
Sometimes brand name system bios versions don't display the actual maker of the bios siftware on the screen while booting , or they give it their own name.
Brand name system bios versions are often at least a bit different from the bios version used by the mboard manufactuer. It can be a huge mistake to flash the bios of a brand name system with the mboard manufacturer's version, when the mboard being used is identical to the manufactuer's retail model, especially if they use a different brand of overall bios version, and visa versa. E.g. HP and Compaq brand name systems often use Phoenix bios versions - the mboard manufacturers other than Intel usually use Award or AMI bios versions.
Sometimes, especially common for laptops, there are far fewer things you can set in the bios Setup in brand name builder bios versions.
Brand name system builders usually use their own specific version of the bios, and the key you press to get into the bios Setup is often different from that used by the mboard maker's bios version, if the mboard manufacturer has an identical retail model.
Sometimes smaller brand name system builders don't bother to modify the specific bios version on the mboard model - it's identical to that for the retail model of the mboard maker's, and the key you press to get into the bios Setup is the same as the mboard maker's.
In most cases, the mboard was not made by the brand name system builder - it was supplied to them by a major mboard manufacturer. Sometimes it's an OEM mboard model in a brand name system - made only for brand name system builders - the mboard manufacturer has no support for that mboard model - only the brand name system builder does, if at all.
You/we can often determine who actually made a mboard in a brand name system desktop, but that's usually difficult to determine, or impossible to determine, for laptop mboards.
"I am just too worried about accidantly doing something wrong while entering or working with BIOS."
You have to deliberately choose to Save the changed bios settings, otherwise the settings stay the same as they were before you looked at the bios. As long as you don't absent-mindedly press keys, you can't go wrong. If you're not sure what you're doing in there, ask us, describe what you want to set.
You can't change the current temperature, voltage, and fan speeds in any case - they're generated by sensors on the mboard, and interpreted by bios code to read appropriately. The bios code is often tweaked to make sure those are accurate. SpeedFan and similar software may generate slightly different readings - you can often adjust the settings in the software to have them match the readings you see in the bios.
Speedfan and similar often assume the mboard manufactuer is using the chip makers designated connections for multiple temp, fan, and voltage readings. Sometimes the mboard manufactuer does not adhere to that.
If the labelling for a reading in SpeedFan or simliar for a temp, voltage, or fan rpm is different from in the bios, change the labelling in SpeedFan or similar to match the readings in the bios.
NOTE that if you have or can find a manual for your model, there is often descriptions of what the specific bios version's settings are, and sometimes descriptions of what setting non-default settings do, in the manual. Mboard manufacturer's manuals often have more info about that than brand name system manuals do - sometimes brand name systems have no or almost no info about that in the manual.
"No mouse in the BIOS. You use the keyboard."
I've seen a few bioses you can use a mouse in, 486 and up, but they're certainly not common. In that case, sometimes only a PS/2 connected or serial connected mouse will work.
"When I did start downloading it, it stopped and a message appeared "this download can damage your computer", so I discarded it."
That sounds like a generic message generated when you attempt to download a file that has certain file extensions, e.g. , if it's got an .exe extensions, because that extension is known to be associated with a type of file commonly used by malware. It's probably auto generated by something built into your internet browser version, or your anti-malware software.
Some email programs do that too when you click on an attachment to an email.
When you are accessing a definately legitimate web site such as the one for SpeedFan OtheHill provided, you can be quite certain the download is not malware - just ignore the message and download it anyway.
In any case, you can scan individual files if you so choose in your anti-malware software, if you're suspicious of them.
