VirtualBox - accessing SCSI (sym(4))

My yesterday’s attempt to get Win95 running in a VirtualBox succeeded. But it’s slow on my AMD Athlon X2 FreeBSD machine
Maybe one would have to tweak assembler optimizations in the port build? Or I’ll get me a better CPU+MB+memory.

Before I continue with getting a Windows XP image to run in VirtualBox (yes, I would have to run some old Win32 program that accesses the SCSI bus (program is called esiWin and requires some older DLLs - WNASPI32.dll/Adaptec, which don’t seem to be available under
Windows 10 and I don’t have the hardware available anyway with a Windows 10 system).

So in said above FreeBSD system (which I upgraded to 12.1before yesterday) there is a 2520 Symbios (sym(4) card) which can access the SCSI devices, an SCSI-CDROM and an ESI-4000 sampler (equipped with an SCSI2CD San-Disk unit). That’s the scene behind it.

The idea is to access the SCSI controller/Bus from within VirtualBox.

Would that work at all?
