Please could you check if this Guru meditation persists with VirtualBox 1.6.2?

I will retest. Anyway, disk image with FreeDOS that can be used for this test is attached with bug report #1599 ( http://www.virtualbox.org/ticket/1599)

 http://www.virtualbox.org/wiki/Changelog doesn't list any point that can fix this issue. I am going to retest.

I forget to notice that I run VirtualBox on CPU WITHOUT support for HW virtualization (P4 CPU), I didn't write this information here and I think it can be important (several bugs related to HW virtualization, AMD-V/VT, were fixed in version 1.6.2).

Retested with VirtualBox 1.6.4. I see a change in behavior, no crash now but after reboot all messages are printed to the first line only. This is not good. It could be a FreeDOS bug but I don't see this problem under VMware player so I think it is bug related to VirtualBox or VirtualBox BIOS. Bug related to warm reboot.

I see the issue only when I reboot PC from software (reboot command in FreeDOS; FDAPM warmboot). When I use VirtualBox reboot command (menu or HOST+R), it is OK. FreeDOS command "FDAPM COLDBOOT" works fine too.

It is simple to reproduce. I just start FreeDOS and after that enter reboot command that is a BATCH file with "FDAPM WARMBOOT". 100% repeatable.
