GetSetDetailedVMError

include vmm.inc

mov     ebx, VM       ; VM handle or 0 if Create_VM error
mov     ecx, GetSet   ; zero if get, nonzero zero if set
mov     eax, Error    ; error code if ecx nonzero
mov     edx, RefData  ; reference data if ecx is nonzero
VMMcall GetSetDetailedVMError

mov     [RefData], edx  ; reference data for the error code

Sets detailed error code for a virtual machine crash or start-up error. This service is only available for Windows version 3.1 or later. Uses EAX, EDX, Flags.

Returns with the zero flag clear if detailed error information was found, set otherwise. If the zero flag is clear, the EAX register contains an error code and the EDX register contains reference data associated with the error code.

Handle of the virtual machine. If this parameter is zero, the service gets or sets error information for the Create_VM message.

GetSet

Value specifying the action to take. If zero, the service retrieves error information. If nonzero, the service sets error information.

Error

Error code to set. This parameter is ignored if the GetSet parameter is zero. There are the following error code values:

Value	Meaning
GSDVME_CrtNoMsg	Problem creating the VM. The system will not display any error message; it is the responsibility of the virtual device to use the SHELL_Message service to display a custom error message.
GSDVME_DevNuke	Device-specific problem.
GSDVME_DevNukeHdwr	Device-specific problem caused by software running in the virtual machine.
GSDVME_InsMemEMS	Available EMS memory is less than requested; set by the virtual V86 mode memory manager.
GSDVME_InsMemV86	Insufficient V86 memory; set by the virtual V86 mode memory manager.
GSDVME_InsMemV86Hi	Insufficient high MS-DOS memory; set by the virtual MS-DOS manager.
GSDVME_InsMemVid	Insufficient base video memory; set by the virtual display device.
GSDVME_InsMemVM	Insufficient base virtual machine memory for control block or instance buffer.
GSDVME_InsMemXMS	Available XMS memory is less than requested; set by the virtual V86 mode memory manager.
GSDVME_InsV86Space	Available V86 address space is less than requested; set by the virtual V86 mode memory manager.
GSDVME_InvalFlt	Invalid fault.
GSDVME_InvalGpFlt	Invalid GP fault.
GSDVME_InvalInst	Attempt to execute an invalid instruction.
GSDVME_InvalPgFlt	Invalid page fault.
GSDVME_InsMemDev	Could not allocate base virtual machine memory for device.
GSDVME_NukeNoMsg	Fatal problem forcing the VM to be destroyed. The system will not display any error message; it is the responsibility of the virtual device to use the SHELL_Message service to display a custom error message.
GSDVME_OkNukeMask	Reserved for the exclusive use of the virtual MS-DOS manager.
GSDVME_PrivInst	Attempt to execute a privileged instruction.
GSDVME_UserNuke	User requested running virtual machine be terminated.

Error values that have the high word set to 2 are intended to be used when a virtual machine fails on start up.

RefData

Reference data to set. If the Error parameter is GSDVME_PrivInst, GSDVME_InvalInst, GSDVME_InvalPgFlt, GSDVME_InvalGpFlt, or GSDVME_InvalFlt, this parameter is the address of a VMFaultInfo structure that contains data associated with the error. Otherwise, RefData is a pointer to an eight-character buffer giving the name of the virtual device that reported the error.

This parameter is ignored if the GetSet parameter is zero. This parameter is zero if there is no associated reference data.
