Hi,
under GO32V2 i want to call BIOS PnP function with entry point
db $FF,$1E; dw PnP_EntryPoint
or
call DWord ptr [PnP_EntryPoint]
but always i got error "SIGSEGV - segmentation violation".
PnP_EntryPoint (type pointer) is normally somewhere in BIOS area at
F000:xxxxh.
In PnP specification i found this:
"If this function is called from protected mode the caller must
create a data segment descriptor using the 16-bit Protected Mode data
segment base address specified in the Plug and Play Installation Check
data structure, a limit of 64k, and the descriptor must be readable and
writable."
But i don't know how can i do that
-> "make a readable and writable data segment descriptor".
And the second problem is how can i make a pointer
"PnP_EntryPoint" to this real memory area.
Under real DOS with BP7 it is O.K.
Sorry, i know this is not really question to FPC, but maybe somebody
could help me. The same problem i got with calling ASPI entry point.
Thanks
Lubomir Cabla/CBL
