Hmm, I think I can interchange the cable of E250 and server to test(The Switch is not accessible to me now)On Wed, 2008-01-23 at 09:38 +0800, Hero_xbd!.RRR wrote:I have successfully pulled the files through TFTP to my PC in dormitory (TFTP server is at lab). Does it infer there is no problem here?This seems vaugely familiar. I have a vauge memory of having problems getting a Sun machine to netboot and finding out it was a cabling problem. Have you tried swaping the Sun machine for another boxen and pulling the netboot file from the server? This should tell you if it's a cabling / switch problem.That depends on the architecture of the network. If it's something like this: PC in dorm <--> ... some network ... <--> switch <--> server ^ | | V E250 (Where arrows are ethernet cables) then you will have tested all but the cable that goes from the switch to the E250. If your topology is different then what you have tested will be different.
E250 is using an old scsi interface. Here in my university you can rarely see scsi, and if there is one, it is of new interface...PS If you get really stuck netbooting, you could pull the disks, dump a minimal filesystem on them and then boot from disk.
I myself is not fimilar with scsi, I do not know the specification of the bus(I know they're different, one is old one is new)
Oh, perhaps I can have an IDE PCI card on E250 use an IDE HDD to boot. While I am still curious about what is blocking me from netbooting...
