Re: [9fans] Installation CD Problems
I've been trying to install Plan 9 on my most used computer here, but the install CD I've made has been giving me problems (I've used Nero on Windows to create it): when I try to boot into the Live CD, at a very early stage (actually, just after asking root is from), it reports I/O read error messages, and continually does so, unable to boot into the Live CD. [...] And yet, the CD data is readable from a mount within Linux. assuming that your linux test was on the same machine, that certianly sounds like a bug. could you send me pci or lspci -nvv output. i'm wondering if you have an ahci chipset. older versions of the ahci driver / 9load driver have some trouble with some newer ahci wrinkles, like staggered spinup and advanced power management. i believe that i've gotten to the bottom of anothy's problems reported in http://9fans.net/archive/2009/01/370 i can work with you offline. the code's not ready let loose. - erik
Re: [9fans] Installation CD Problems
so I immediately go into rc with `!rc' at the install rio window, and upon trying `mount /dev/sdC0/data', I again get the same I/O read error message, so it is unable to mount the data. And yet, the CD data is readable from a mount within Linux. How is the CD drive installed? /dev/sdC0 seems definitely wrong for the CD. If it's the master on a second IDE controller (the most common case), you want /dev/sdD0. If it's the slave on the first controller, you want /dev/sdC1. BLS

How is the CD drive installed? /dev/sdC0 seems I might have forgotten what it was. I'll check soon and get back to you on that. BLS Thanks, ak

If it's the slave on the first controller, you want /dev/sdC1. great point. i don't think there's any problem with running a cdrom as ide0 device 0. but iirc, the plan 9 installer is particular about where the cdrom is installed. the last time i tried sdE0 (ide interface) was not an acceptable location. if someone's itching for a project, the installer could use a little touch up. - erik

Re: [9fans] Installation CD Problems
OK, so I'm just getting caught up on the replies here so far. As far as /dev/sdC0 goes -- BLS is right, it was really /dev/sdD0, and I remembered incorrectly. That is, the CD ROM Drive is, indeed, second IDE master.
Re: [9fans] Installation CD Problems
The only problem seems to be with the plan9.ini file, /sys/lib/dist/pc/plan9.ini.cd, which specifically asks to boot from /dev/sdD0 If I understand the handling of the bootfile and bootargs, multiple entries for most variables cause a menu prompt. But that does not apply here, you're referring to the second option, the first, [install], boots off the floppy. Where is the plan9.ini that the floppy consults? ++L
