#17371 duplicate Option to disable NIC option ROM wbpayne
Description

I would like to request that an option be added to disable the NIC boot rom.

Background: I run a couple of really old operating systems on VirtualBox, namely Windows 98SE and DOS 6.22 plus Windows 3.1. EMM386 cannot allocate a page frame because of the fact that the NIC option ROM is mapped at E200. I also have problems maximizing the amount of UMBs available because of this. Even if the NIC is disabled, this option ROM is still mapped. I think an option to disable network boot and the option ROM would be a worthwhile addition to VirtualBox.

#17368 duplicate 3D Acceleration and Unscaled HiDPI Output bug sjchoi
Description

I have three problems.

[1] "Enabling 3D Acceleration" causes screen detach.

See "3D Acc.png". Steps to reproduce:

1) Install a Windows 10 guest on a Mac host. 2) Enabling 3D Acceleration in Settings > Display > Screen. 3) Boot the Windows guest.

[2] "Enable 3D Acceleration" and "Use Unscaled HiDPI Output" causes screen detach and distortion.

See "3D Acc & Unscaled HiDPI.png". Steps to reproduce:

1) Install a Windows 10 guest on a Mac host. 2) Enabling 3D Acceleration and Use Unscaled HiDPI Output in Settings > Display > Screen. 3) Boot the Windows guest.

[3] Using Unscaled HiDPI Output in Integrated Graphics is very slow.

Steps to reproduce:

1) Install a Windows 10 guest on a Mac host. 2) Use Unscaled HiDPI Output in Settings > Display > Screen. 3) Uncheck 3D Acc to use Internal Graphics. 4) Boot the Windows guest. 5) Set "Custom Scaling" to 200% in Settings > System > Display > Scale and layout in Windows. 6) Log out and in to apply.

In this state, the virtual machine is very slow and laggy. Can there be any optimizations so that I can use a retina Win 10 guest without any lag?

7) It goes well if disable "Custom Scaling" in the guest and set "VirtualBoxVM.app" as "Open in Low Resolution" in the host. See "Low Res.png".
