That doesn't seem to be a VirtualBox error message. I have no idea what "device IOS" is.

I suggest that you use Google for guest OS error messages. For example the post by LoneCrusader in the attached discussion looks promising.

Hi,
I've had the same issue as you but managed to resolve it. Let me reinstall my Win95 VM so I can give you the exact steps and I'll be back to you shortly

Ok, I've found the solution, so I think it's worth sharing to help you and other fellows.

The reason the Win95 kernel crashes is because of a well-know issue: Intel CPUs above 2.1 GHz aren't supported (and AMD ones aren't if >350 MHz) and will cause the network driver (NDIS) to crash during boot.
Microsoft has released a patch for it, but you need to run it within Win95. Luckily, a guy named "LoneCrusader" on the MSFN.org forum has re-packaged it into a convenient bootable ISO.

Steps to solve the "Windows Protection Error" when running Windows 95 on VirtualBox

1) edit the VM settings --> Acceleration --> disable VT/nested paging
2) download this zip file: http://www.tmeeco.eu/9X4EVER/GOODIES/FI ... _FINAL.ZIP
3) get the FIX95CPU.ISO file from the zip
4) attach the iso file to the CD drive of your Win95 VM (as usual)
5) reboot and you'll get a red on black screen. It's fine :)
6) decline to read the "readme" (better to read it later within Windows) and go ahead
7) reboot when prompted to do so, detach the ISO, reboot again and enjoy Win 95 working fine :D

The OP has not visited since August, so I'll thank you anyway for these posts.

(though IMHO the better solution is to ditch anything earlier than Win98SE :twisted: )
