hey friends, Recently I purchased Compaq Presario SR1722IL and I tried to install Centos 4.0 on it but it started showing errors like: Uniform CD-ROM driver revision: 3.20 Combo SOLTC-4836k ATAPI CD/DVD-ROM drive hdc: IRQ Probe failed (Oxfcfa) hdd: IRQ Probe failed (Oxfcfa) hdc: lost interrupt I tried installing FC4 also but same problem persist. Windows 2000 & Windows XP are already installed on the same system that means the Combo Drive is working fine. Then I tried installing SUSE 10.0 with the same Combo Drive and I faced no problem except when it starts "Gnome or KDE" it shows Frequency out of range.. What is the reason that FC4 and Centos4.0 are failing with the installation? What should I do to get rid of the problem ? Thanks & Regards Ankush Grover -------------- next part -------------- An HTML attachment was scrubbed...
