Describe the bug

I tested the Trident 8900B, 8900D and 9000. And found that the machine rebootS after loading HIMEM.SYS device driver.
I tested on 3 different buildS. On 286 machines, for some reason, the HDD is not recognized by the VM with the Trident video card but works fine with the Sigma Color 400.

NVR+CFG:
386 DX trident 8900D.zip

HDD:
386 Win 31 Trident 8900D.zip

To Reproduce
Steps to reproduce the behavior:

1. Start the VM
2. Boot the machine
3. The VM restarts after loading HIMEM.SYS

Desktop (please complete the following information):

• OS: Windows 10
• 86Box version: 4.0.0.4892
• Build information: old dynarec Win 32

Additional context
Worked fine on build 4.0.0.4849
