I've never had it cause issues. BIOS has always recognised the HDs and linux, until now, has always been more than happy to work with them. This is across many different mbs, ide chips and hds. On this server a lone hdd has been the case for 4 years and has worked fine. > Essentially, fixing the hardware config to set the drive for master if > it's the only device on the channel is likely the best solution overall. It is what worked, after a lot of futzing around. Still, this is a regression (from the pov of someone who just had to futz). Before whatever change was made things were fine and futz-free. -- "A search of his car uncovered pornography, a homemade sex aid, women's stockings and a Jack Russell terrier." - http://www.news.com.au/story/0%2C27574%2C24675808-421%2C00.html
