Hi, I think you will have to take a debug log, as described in https://www.reactos.org/wiki/Debugging , with a method adapted for PCEm v12 if possible (an alternative would be to boot with the debugger available on screen...)

Hi hbelusca.

PCem does not support COM port but the connection of the mouse.

Can you make dump of PCI bus layout with pcidumpc (http://alter.org.ua/soft/win/ntpcidump/) ?

If r74131 works, add REGRESSION label.
If not, remove G.R..


Yes, duplicate of CORE-11277.

Comment by Alter [ 2017-04-07 ]

Looks like PCem sets Current Sectors/Heads to zero in HDD identify block.
This caused div-by-zero exception.
Please, check uniata_v46e2_to_v46e3.diff

Comment by MiX [ 2017-04-08 ]

Thanks, error fixed. Now add the driver to release.

Comment by ThFabba [ 2017-04-15 ]

r74319 should fix this. Please confirm?

Comment by MiX [ 2017-04-16 ]

LiveCD r74319 - Boot Ok.

Comment by Jedi-to-be [ 2017-04-29 ]

Please resolve this!

Comment by Serge Gautherie [ 2017-04-30 ]

Resolution: Fixed

Please, rather resolve as "Duplicate" (or even "Clone") of CORE-11277.
