I'm migrating some DOS machines to VirtualBox. I use the common NetWare-style IPX stack. The problem is that VirtualBox doesn't emulate any of the network-adapters that I have drivers for. So, where do I find a driver for any of the network-adapters that VirtualBox can emulate?

Doesn’t VirtualBox have Guest Additions for DOS? – Synetech Sep 1 '12 at 22:05

Ben Armstrong, Virtualization Program Manager, suggests


then running

  • LSL
  • DC21X4

in that order.

I cannot get it to work. The driver is for Intel 21x4 network-adapters. But VirtialBox (4.0.12) only supports Intel 8254 and PcNet 79c97x. I just get the message: "DC21X4-DOS-50: Board not found in system". Am I missing something? – Fabel Oct 28 '11 at 18:13
