I was using DS sucessfully on my old laptop (Winbook running ME) that is on its way out. I bought a Dell inspiron 8600 running XP. I know XP has problems with DS and thats why Im using a bootable floppy directly to DS. I get it to run but the readings are all screwy. 60ms inj pulse width at idle, block cells reading incorrectly etc along with others. I checked the boot floppy (the one someone posted and made form the BB) on my old PC and it works correctly. Is it a com or lpt port adjustment? I remember using a friends Dell a few years back with the same problems. Any suggestions solutions would be appreciated. Thanks.
