During the file install of RH7.2 When the Disc2 get to the Tetex soft ware the install stalls. Every thing preseading this went smooth. and I like the improvements to disc-druid.
This install is on a Asus p3b-f (440BX) and a search showes other systems with 440BX and 7.2 working together. My disc2 passed the md5sum, but I am right now downing another copy just to be sure.
i'm pretty sure that maybe you had a bad burn with your second disc. i don't think it was your iso that was bad, but the actual media that you burned it on to.
and yes, rh7.2 works fine with a 440bx chipset. my abit be6-ii works great under linux.
