Hi list, I have the unfortunate luck of wanting to install Linux on a Dell optiplex 320. This machine seems to be as anti-linux as they come! Problems faced: 1- Sata disk not recognized WorkAround: pass pci=nomsi, or all-generic-ide (depending on newer/older kernel version) 2- Grub does not boot!! WorkAround: Use lilo 3- Machine doesn't have PS2, only USB keyboard/mouse. USB does not work, the following errors are generated ohci_hcd 0000:00:13.2: OHCI Host Controller ohci_hcd 0000:00:13.2: USB HC TakeOver failed! ohci_hcd 0000:00:13.2: can't reset ohci_hcd 0000:00:13.2: init 0000:00:13.2 fail, -1 ohci_hcd: probe of 0000:00:13.2 failed with error -1 I need to install RHEL4 (much better), or an older Fedora (4?). This is because of the CAD software that will run on this machine. I have not found any work-arounds for such problem (only one that uses ohci-hcd parameter no_handshake, which is not understood by 2.6.9 kernel). If anyone is aware of any un-official kernel patch that solves that issue, kindly let me know. regards
