Top HAT an alternative to Dual Bios.
[edit]I have top hat and was looking for some info. None here though.
Anyone know of this subject please give us your two cents. http://www.wimsbios.com/phpBB2/viewtopic.php?t=7385&
IBMBIO.COM
[edit]When I click on the link "IBMBIO.COM", I get this:

Eh?

UEFI
[edit]See UEFI. It says A common misconception is that UEFI is a replacement for BIOS and explains that UEFI-based motherboards come with BIOS ROMs. I saw elsewhere a page in the Intel website stating that a UEFI is an interface between the operating system and the system firmware and I am nearly certain that firmware is the BIOS, but I closed that page.

Okay, see Unified Extensible Firmware Interface. It says the UEFI defines an interface between an operating system and platform firmware. There are many possible references saying that firmware is BIOS. Sam Tomato (talk) 02:51, 4 February 2022 (UTC)
The Alternatives and successors section says that Intel announced that it would remove legacy BIOS support without any authority for that. I have provided an authority from them indicating that systems still have BIOSs. Sam Tomato (talk) 03:34, 4 February 2022 (UTC)
That osdev.org article uses dodgy terminoloy. See Barlop's answer here that mentions that article. https://superuser.com/questions/1450261/does-uefi-run-on-top-of-bios — Preceding unsigned comment added by 86.1.49.43 (talk) 03:57, 21 September 2023 (UTC)
Question!
[edit]What exactly happens if your computer gets unplugged during a BIOS update and does that problem affect laptops?  TheMaggster (talk) 05:23, 24 July 2023 (UTC)
- it will corruptBold 105.112.189.112 (talk) 16:44, 5 August 2023 (UTC)
- Thanks for the answer. TheMaggster (talk) 16:45, 6 August 2023 (UTC)
Shouldn't this paragraph be adjusted
[edit]It says "The BIOS firmware comes pre-installed on an IBM PC or IBM PC compatible's system board and exists in some UEFI-based systems to maintain compatibility with operating systems that do not support UEFI native operation."
It could be adjusted to note past tense, BIOS CAME pre-installed, rather than comes pre-installed. And the description about the BIOS existing in some UEFI should be said far more accurately and clearly. The paragraph below has that adjustment.
The BIOS is firmware that came pre-installed an IBM PC or IBM PC compatible's system board. Nowadays systems use UEFI rather than a BIOS. UEFI is the modern type of firmware that has replaced BIOS. Many UEFI-based systems have a "Legacy mode", also known as CSM Mode, which allows the UEFI to emulate a BIOS if the user requires it e.g. to run an older OS. 86.1.49.43 (talk) 03:51, 21 September 2023 (UTC)
Wouldn't that be much better? — Preceding unsigned comment added by 86.1.49.43 (talk) 03:52, 21 September 2023 (UTC)
BIOS reverse engineering
[edit]"The BIOS originally proprietary to the IBM PC has been reverse engineered by some companies (such as Phoenix Technologies) looking to create compatible systems."
There is a complete assembly listing of the original IBM PC/AT BIOS in IBM's PC/AT Technical Reference Manual. This means that no reverse engineering was required. 106.69.154.248 (talk) 23:02, 30 January 2024 (UTC)
