Duly impressed – thanks B-O!

Hi Gerard,

I send our legacy BIOS for Max and Turbot to your email address at tekmagic.net <http://tekmagic.net> 

Best regards,

Hi B-O

Interesting...

Which BIOS do you use to boot MSDOS?

Curious....

Hi Gerard,

Please let me know how you are doing with this and also the MSDOS boot.

For your info, I use MSDOS a lot on Minnowboard Max/Turbot booting from SD card or USB thumb drive. It’s the best way to test the BIOS and the firmware.

Best regards,

B-O

Hi B-O,

Thanks for this feedback/tip. Will make sure we check this out as well.

Much appreciated.

Gerard

Hi Gerard,

In case you have problem with a second NIC in the PCI expansion bus using
the silver jaw lure, the problem is the violation of PCI timing as the
PLTRST# signal is not used to reset the NIC. They use the PWROK signal to
reset the NIC and on a reboot the PWROK remains high. In the case of full
reset from PCI reset register the PWROK gets initial low and then high, but
violates the PCI bus reset protocol as the RESET# signal should remain low
for at least 100 mS after power (PWROK) is stable.

Best regards,

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
