We are migrating from Fermi Labs linux distro to the Centos 3.6 distro. So far all of the Dell's we have installed on have worked fine but we have two generic servers that are using Tyan Thunder K7X motherboards with built in Adaptec Ultra 160 SCSI using AIC7899 chipset. When we try to install on these systems the install cd seems to lockup loading the AIC7xxx driver. Adaptec says they do not support OEM embedded products and Tyan says that any embedded firmware is included in the bios upgrades which we have upgraded. We can migrate "online" by following the White-box to Centos migrate instructions and that works fine but it worries me that if I lost a hard drive in one of these systems I could not install Centos directly. Any suggestions for work arounds? Thanks Rich A.
