[MinnowBoard] How does one run MS-DOS on a MinnowBoard MAX (or turbot)? (Emir Elkholy)

Hello,

Yes, I have developed one that I use for the same purpose. Where can I send it?

BTW, if you don’t attach any boot devices the internal OS (wDOS) will run. If you write SMT <enter> at the prompt and choose ”PCI Device Information” you will be able to see all the PCI devices found. If you move to any PCI device in the list and press <enter> you will be able to see all the details about the device.

wBIOS always initializes all PCI device and assign resources to them. So any PCI device found are ready to use when the OS start. This is different than UEFI BIOS that doesn’t do much useful at all. Despite doing all initialization, wBIOS is about 10 times faster than UEFI BIOS.

The SMT tool, is only a demonstration that our BIOS contains a 32-bit OS with a file system. That OS can be used for many purpose, like backup and restore or stand alone thin clients etc. It’s always included.

In fact with our tools, you can add your own applications without changing the BIOS binary and rebuild a new flash image with your applications. 

wBIOS was developed from scratch to be used for embedded and consumer applications and as the BIOS image is only 64KB, we have plenty of room in the flash that we use for OEM hooks, OS and applications. 

Best regards,

B-O

Is there a common tool that runs on DOS that can output all of the devices on the bus? This may help us with our issue of having the NIC recognized in Windows CE. Also, is there a known rev of the Minnowboard Max Turbot that has the NIC issue resolved (I read earlier that some nic issue was fixed in later boards). Just wanted to see if our board is one of the newer ones.
