Where to locate previous BIOS versions for downgrading your laptop to BIOS v1.15 or earlier?
Where to locate previous BIOS versions for downgrading your laptop to BIOS v1.15 or earlier?
Virtualization on Windows offers one method to install Ubuntu alongside Windows. It functions, but eventually this device may become too sluggish.
Keeping Ubuntu as the primary operating system while running Windows in a VM could provide better speed. That idea seems more appealing to me and I really want to try it on this laptop.
However, if there are no longer any older BIOS versions available for this machine (such as ZRT115.exe or earlier), I’m also thinking about flashing a BIOS from another identical Acer laptop that matches the Aspire E5-573 specifications. This would help reduce issues and minimize errors, and I’d hope to avoid damaging the device while still being able to install Linux.
If Linux VM operates on Windows 11, think about reducing it to Tiny10 to minimize resource usage and improve speed.
Thanks for the update! I also discovered Tiny11 is out there, which is more of an updated DIY option, though not too complicated. However, since Windows updates are needed to unlock it, I'm a bit cautious about using it right now. Still, I'll keep this in mind. I'm still looking through older BIOS versions (1.15 or earlier) and hoping to find something useful soon.
Something that I've been realising just now: If I poke around one of the links , I may just get the ZRT_115.exe I need to downgrade this laptop's bios for good!
Like, take a look at this link from the OP:
http://global-download.acer.com/GDFiles/...ep3=ASPIRE E5-573G&OS=ALL&LC=en&BC=ACER&SC=AAP_2
3 things stand out to me:
The file being downloaded is
BIOS_Acer_1.25_A_A.zip
- the file's id is
635766982144057569
- Everything else after it points to the file for the Aspire E5-573G model
The same thing I find for the other BIOS version of my model:
https://global-download.acer.com/GDFiles...ep3=ASPIRE E5-573G&OS=ALL&LC=en&BC=ACER&SC=PA_6
- File being downloaded is
BIOS_Acer_1.37_A_A.zip
- its id is
635931764613099898
- Everything else after it points to the file for the Aspire E5-573G model
https://global-download.acer.com/GDFiles...ep3=ASPIRE E5-573G&OS=ALL&LC=en&BC=ACER&SC=PA_6
- File being downloaded is
BIOS_Acer_1.35_A_A.zip
- its id is
635877484326516467
- Everything else after it points to the file for the Aspire E5-573G model
https://global-download.acer.com/GDFiles...ep3=ASPIRE E5-573G&OS=ALL&LC=en&BC=ACER&SC=PA_6
- File being downloaded is
BIOS_Acer_1.31_A_A.zip
- its id is
635864585890195617
- Everything else after it points to the file for the Aspire E5-573G model
Then there's the BIOS 1.25 mentioned already above
Based on this known pattern, I feel there should be a way to download BIOS 1.15 & older for the Aspire E5-573G with the following link:
https://global-download.acer.com/GDFiles...ep3=ASPIRE E5-573G&OS=ALL&LC=en&BC=ACER&SC=PA_6
- File being downloaded is
BIOS_Acer_1.15_A_A.zip
- its id is
unknown
(that's why acerid is just a
string of 18 Xs
)
- Everything else after it points to the file for the Aspire E5-573G model
Without the acerid,
the link will not work at all
. Is there a way to check for the 18-digit acerid I need for this BIOS to download besides just trying a bunch of random numbers?
I really want this laptop to have a fresh new life by having Linux on it & not get slowed down by Windows due to laptop's age & all.
From your samples it indicates each file possesses its distinct acerid
