Moderators Jake Lo Posted November 17, 2021 Moderators Share Posted November 17, 2021 What version of BIOS? What's the display's resolution? You can find these in the BIOS Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted November 17, 2021 Moderators Share Posted November 17, 2021 Try this, it's for BIOS A24 with Low Resolution display Intel Wifi may or may not work, I've included it anyway. EFI-loRes-A24.zip Link to comment Share on other sites More sharing options...
