Re: e7450 la-a963p motherboard add bios option

thank you, but this is for the E7450 i5, which has a different motherboard. Mine is the e7450 i7. as I explained, I tried both pcie and sata ssds nvme b+m key 2242, and it failed for both of them in the i7 version. That's why I'm looking for modding the bios.

Re: e7450 la-a963p motherboard add bios option

no idea about modding the bios to activate the port WWAN? thank you.

I have a Dell e7450 i7, the one with the msata port only, not the 2.5 sata port which is the i5 version of E7450. I tried to install a ssd in the WWAN port of that E7450, as I did in a 5580 (in that case both sata and pcie worked 2242 B+M key!). NONE of the ssds I have (sata or pcie b+m key 2242) worked in the WWAN port of the E7450 (Bios and Windows). I wonder if it's something locked in the Bios because nothing is visible in the Bios. The Bios suggests that only another sata ssd would be accepted if it's a ssd connected to a dell docking station ("esata dock port"), zero mention in...

Hello,

Since 2020, Intel provides UEFI 3.0 bioses without legacy CSM support. It means that for example, Dell does not provide anymore laptops since the xx80 series with Bioses including full legacy CSM support, but only with UEFI (some still provide legacy for USB only). It's true since 2019/2020 with Dell.
I REALLY want full legacy support CSM (not with limited usb only), so I wonder if new dell bioses of laptops sold in 2021/2022 can be modded to get full legacy support.
If it's not possible with dell, do you know if there is still a brand providing new laptops...

no idea? thank you for your advice.

Re: Dell Latitude 5580 (LA-E091P)

Hello,
Please I'm not very good with mods but I'd like to ask you a question. The new 5590/5490 and newer (5500 etc) laptops don't allow to choose legacy mode (not UEFI) in the bios. The last serie offering this option is the previous one, like 5480, 5580 - Dell explains this on their website. Now, would it be possible to modify the bios of 5590 laptop to "activate" this option, to have it back in the bios? thank you for your answer.

Hi,
I've experience with computers for about 25 years. I realized that you have to know how it works if you wanna get the mst of them. This knowledge is hard to find sometimes. "Putting the hands in the grease" today is not encouraged, but personnaly it's this way that helped me the most in life. I'm impressed with what I read on this forum. I hope I'll be able to share some of my experience too.
