T540p BIOS v2.21 (gmuj18us) checksum failed.

2015-10-30, 23:29 PM

Hi,

 

I downloaded the latest bios for the T540p, both (Windows and bootable CD) versions have a different checksum to what's stated on the Lenovo website.

 

Can somebody please confirm?

 

I'm getting;

 

sha256sum gmuj18us.iso
995fa1cf8e543ba3bf584fabb94e4a7716be5d630028b2d496a917454cdcffa2  gmuj18us.iso

b40b195b9637fe4a389f6d3b1dabeebd33ba43fd2c4535785130e3016a22ffe9 (Lenovo website)

Filesize: 22,392,832 bytes.

 

sha256sum gmuj18us.exe
00207a46f7ff7f23fe29a8b216f7d50af276a4ce20c41f676b1552e7e61f982b  gmuj18us.exe

9301b9520205c6d5f8272888c416c4a811a9dad318cb7f8e75b0a86fdc04beb5 (Lenovo website)

Filesize: 5,916,920 bytes

 

Thanks.

Anybody?

 

These are the files, checksums for both are wrong (sha1 and sha256).

Regarding the checksum data here:  http://support.lenovo.com/us/en/downloads/ds038147

I agree with you, something is wrong.  I'm asking our publishing team to check it.  Sorry for this trouble.

Yes, I'm certain it's wrong/old hash info.

I downloaded a v2.21 gmuj18us file in early November...since then the file name dropped to 16 and now 17, both versions of the BIOS less than 2.21 so I can't install them...what gives?  How did I download and install file 18 with BIOS 2.21 (and someone else had a checksum failure on it!!!) but now I'm getting lower version numbers...
