I've tried to install both 
7.0-BETA4-i386-bootonly.iso and 
7.0-BETA4-i386-disc1.iso

on a Dell Optiplex 745, Model# DCTR with

acd0: CDROM <TSSTcorp CD-ROM TS-L162C/DE05> at ata3-master UDMA33

The booting doesn't get past the acd0: TIMEOUT - READ_BIG retrying
error.

6.2 installs fine.

Any ideas on what to try?

Thanks
robert
