And, for Virtual PC, we get a "READ ERROR 01" which means "Invalid
command" (https://en.wikipedia.org/wiki/INT_13). Same.

For the mailing list: We discussed this in IRC just now.

It seems that virtualbox doesn't support BIOS 0x13 interrupts for
"Extended Read Sectors" calls.

We guessed that from the fact that this message appears, but not the
following "Checking long mode".

Hi Alex,

The new version boots fine on qemu under windows 7 x64. Under
virtualbox on the same platform, get stuck with a black screen that
says Loading PilOS with nothing else displayed

This is how I converted the image

"c:\Program Files\qemu\qemu-img.exe" convert -O vmdk x86-64.img  x86-64.vmdk

The symptoms are the same when I use vboxmanage to convert:

c:\Program Files\Oracle\VirtualBox\VBoxManage.exe convertfromraw
x86-64.img x86-64_vbox.vmdk --format VMDK
Converting from raw image file="x86-64.img" to file="x86-64_vbox.vmdk"..
Creating dynamic image with size 684032 bytes (1MB)...

It still freezes on the black screen Loading PilOS
