## Questions & Answers

**Q: Please inform if the PCI-e card is compatible with IBM X3500 M4 7383 server with Operating System Windows Server 2008 64 bits**
A: I'm sorry, but I cannot confirm that it will work on your server running Windows Server 2008 64 bits.  I am running my 4 port card on a Windows XP 32 bit operating system.  Perhaps another user can answer your question.

**Q: Compatiable with Windows 8.1 or 10 ?**
A: This does have Windows 8.1 drivers available.  Windows 10 drivers are not currently available.

**Q: Does this now have Windows 10 drivers? I haven't seen any questions in a few years.**
A: I have installed the card on a Windows 10 pro PC

**Q: You say this device works with dos, but uses irq sharing.  i use a dos app that requires using the standard i/o and irq settings.  will this work?**
A: I could not get this device to work on my computer.  I have a digitizer that worked on an old computer and I bought this device so I could use the digitizer on a newer computer and could never get it to work.
