Video Driver

You need the "MISTERFB.DRV/INF: Windows Video Driver" referenced on ao486_MiSTer. Once you've downloaded them, I suggest creating a disk image (see: Ao486_Core_Info#Floppy_Disk_Images.2FGetting_MISTERFS.EXE_on_a_VHD). After booted into Windows 95, Right-click the desktop->Properties->Settings Tab->Advanced Poperties Button. Click the "Change" button in the Adapter Tab. Select "Have Disk" and make sure you've got your image mounted for the A drive. You'll need to select a monitor "SuperVGA 1024x768" worked for me. NOTE: If you're using the default MiSTer resolution of 720p, using 1024x768 will cut off the bottom 48 rows.

Tips & Tricks

Boot to DOS Prompt

Change "BootGUI" to 0

attrib -s -h -r -a c:\msdos.sys
edit c:\msdos.sys
attrib +s +h +r c:\msdos.sys

You can type 'win' at the command prompt to start Windows 95.

Troubleshooting

After Initial Install of Win95 OSR2+ boot hangs

Move your VHD to IDE 1-0

In MiSTer Menu -> Hardware: Change hot-swap to different drive than IDE 1-0
