Dear Gurus Thanks for the responses. I'll summarize what I've learned trying to install Centos6 on a Dell Optiplex GX 240 Review: a) I decried the lack of CD images for Centos6. b) I was informed that it's unlikely they'll be produced due to an upstream decision. c) I pointed out that the machine only had floppy, CD and HD boots capability. d) I got a suggestion to use the network method. Results: 1) PXE boot might work, but it seems that it's a lot of trouble setting up a PXE server. I'm still working on it. 2) The NET-INSTALL indeed did work, with the following gotchas: 2a) The URL to enter is not obvious. 2b) I tried the one at Stanford, and at uidaho, but they failed. 2c) Finally, http://mirror.centos.org/centos/6.0/os/i386 worked. 3) SInce I had only a text install, various interesting and important programs were missing: ssh (which apparently is masquerading under the name "openssh-clients"), ftp and perl, which YUM got for me. 4) The module perl-Digest-MD5 was not in the repository. Was its removal intentional, or is it hiding in some other Centos6 repository? 5) The line-by-line notation during bootstrap is no longer shown. This makes it difficult to detect where hangups occur during the bootstrap process. Is there a way to display those notations in real time? Conclusion: I'm still trying David
