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

[Weggerle, Alexander]

Hi Gerad,

The other alternative would be to use a JTAG. There is a JTAG lure(1) available and as alternative it would be even possible to use a so called Agent Based Debugging(2). This just requires a FTDI serial cable and a UEFI Bios compiled with SOURCE_DEBUG_ENABLE. The Intel System Debugger (3) would support this scenario and also allows easily to inspect PCI devices. I used it frequently to debug issues on the Minnowboard. There is a trial version available. 

Thanks,
Alex

Hi Brian,

That is a really good question! :)

We have a couple of PCB designs which one could consider as MinnowBoard MAX "derivatives". On one of the designs (PCB) we have a serious problem with reliable access to the Realtek 8111 NiC, even though "on paper" (schematics,
etc) the two PCB's have the same NiC designs (so in one design everything on the PCB works perfectly while on the other there seems to be some PCI bus access issues to the NiC). We have tried different drivers and other OS level debugging (mainly linux based) but can't seem to isolate the problem (sometimes lspci will list the Realtek NiC after a reboot and sometimes not and when it does get detected/listed by lspci, the whole lspci entry is occasionally corrupted and shows FF FF, etc). Obviously sounds/smells/looks like a PCI bus problem (differential pair impedance, component differences, PCB layout differences, etc..) but we can't seem to isolate it. So we would like to do some "lower level" testing/checking of PCI enumeration and maybe other PCI debugging tools. One of the tools we wanted to play with runs on MS-DOS. 

However, someone just pointed me at UEFI app:
https://github.com/JamesAmiTw/ru-uefi/raw/master/5.17.0284.zip
which should actually be able to run as an EFI app on our normal minnow-derived firmware/BIOS. So need to check that out as well.

If you have any other ideas or pointers please let me know.

Thanks & Regards

Gerard

What is the low-level debugging requirement? Does it need to be run in DOS or just at a level below the OS?

Thanks ... br

Resent with better subject line....

Does anyone know how one could bot MS-DOS on a MBM/T?

Would like to do this for some low-level debugging we need to do. 

I assume it needs a "legacy BIOS" but from what I read the winzent legacy BIOS (which is due soon) is not yet available?

Any help would be appreciated!

Regards

Gerard
