My Personal Oracle is running well . But today My OS got some problem and the autoexec.bat file is corrupted .
SO I did the recovery but unable to remember the content of all the autoexec.bat .

THen the problem comes , PO can not be started but , Any connection will be rejected by ORA-3121 no interface driver .
I belive it's due to the loss of Autoexec.bat .
could anyone help me to fix the problem .

Content of Autoexec.bat : ( I install Oracle7.3 client and Personal oracle7.2 both)

@if exist c:\checkmbr.exe c:\checkmbr quiet (Validate MBR, not a TSR)
@echo off
@c:\zhylqmw\zhylqmw.exe >nul
