Hyper-V: trying to change screen mode gives "General system error"

Description

My "portable" Haiku installation comes up in Hyper-V on Windows 10 using the VESA driver with a screen resolution of 1600x1200, 16 bit color depth. Trying to set a different mode fails with "General system error".

The system was originally used on bare metal on an old laptop that doesn't work any more. I have taken out the hard disk and put it on a USB SATA adapter. Usually I use it now in VirtualBox with "CustomVideoMode1" set. That is the VESA mode that is set. Hyper-V aparrently interprets this as 1600x1200, 16 bit. Or is this maybe an invalid mode?

Off topic I guess, but did you check the CMOS battery of that laptop? If it's totally dead there's chance this battery is the cause. At least I just revived a dead laptop here yesterday by just pulling that battery (will purchase a new one of course)

CMOS battery defective/empty is a known cause for this kind of trouble.

Hi rudolfc, the CMOS battery was probably not the cause. I actually kept it plugged in because the main battery was already essentially dead. It broke literally over night because of a thunderstorm. It "claimed" not only that old laptop but also a wifi router and a switch, so that is the most likely cause. Anyway, I have already thrown away the laptop and only kept the harddrive.

This is probably a duplicate of #13310. Can this be closed?
