Using Internet Explorer the standard VGA display driver with a resolution of 640×480 is too small for browsing. Windows 3.11 comes with standard super VGA drivers up to a resolution of 1024x768, but it does not work on VirualBox. It will result in the "Blue Screen of Death" and Windows 3.11 has to be reinstalled again (Windows 3.11 doesn't have safe mode to recover it).
Because VirtualBox uses a VESA virtual graphic card which is not compatible with Windows 3.11 SVGA-drivers we need to patch them first.
Hint: An already patched SVGA-driver is also stored on the CD-ROM disk Image that I already made for you.
First Step: You need to search and download the Super VGA (svga.exe) driver for Windows 3.11 on the web or follow this link to download it directly:

Your floppy Image need to look like this:

Boot into MSDOS and load your floppy disk Image.
Go to: A:\ and type svga.exe to extract the svga drivers.

After that we need to patch the svga256.drv that was extracted.
To patch: insert after the A:\ prompt "vgapatch p" and hit Enter.
