After installing VIA 4 -in -1 v 4.28 on Asus A7V , the ATA/100 disk seems to have slowed down . I understand that the IDE BusMaster is slower that the Win 98 SE one that it replaced . How do I restore the Win 98 driver ? What is it called ? How can I check which one is actually running ? Also , I don't recall the VIA installation dialogue asking about the BusMaster - is this considered part of the ATAPI dialogue ?
