Thanks Rod, I've made some major changes. I've completely redone the real mode IVT interface. Some bios rely on other bios interrupts to implement bios functions. I have an old Compaq Prolinea 486 which was exhibiting similar problems. It now works fine. Please give the latest version another try.

I think the invalid instruction is a result of whatever is failing in the BIOS call. It seems to be PM int 13h, ah=02 when it does the RM call in pm_int_13h.bios. It never returns from the BIOS call calling the fault interrupt instead. The drive led comes on and it just keeps running. If I insert a very small loop before "call 0:rm2pm", it fails but ctrl-alt-del works... I've tried a whole bunch of stuff. Some things I haven't looked into are 1) your DOS transfer buffer es_buffer 2) BIOS using some BDA value in low memory which is not set 3) good/bad comparison of args for int 13h, ah=02 4) relocated RM IDT by lidt - perhaps BIOS calling aeBIOS RM int instead of BIOS's RM int (You fixed right?)
