disk errors on booting, but not install

disk errors on booting, but not install

[Ethan Grammatikidis]

machine is an x61, this is the first time I'm running it without ide emulation.

using the latest iso, it installed ok, mounting cwfs and running mkfs all went as expected, but it has problems on boot. there are two problems, they may be related or separate, not sure. it's been tried with 9pcf and 9pccpuf on-disk, and 9pcf on iso (actually usb, but i used the kernel from the iso).

problem 1: if it loads the kernel from the hdd it complains about the disk, giving multiple "bad disk" errors (sometimes filling the screen) and repeatedly reporting the disk name. if it loads the kernel from usb it doesn't give these errors. same kernel, the only difference is where it's loaded from.

5f74fcf22a25322029feaee86c21eb38	/shr/sdU7.0/9pcf

problem 2: if i tell it to use the installed cwfs root it just re-prompts for bootargs. i think it also says the partition doesn't exist (like "/dev/sdE0/other doesn't exist"), but i failed to actually make a note of which conditions cause that message. also if the kernel is 9pccpuf it re-prompts for nvram data every time it wants the bootargs.

This is obviously some strange usage of the 
word "simple" that I was previously unaware of.

It sounds like there is some disagreement between BIOS, install and the installed
system. If the settings aren't precisely the same both during and after install you
may run into problems.

Can you show us the contents of your plan9.ini? On my x61t I use this:

bootfile=9pcf

Key here is the combination of *msi=1 and SATA.

mine's a lot simpler:


bootfile=9pccpuf
bootargs=local!/dev/sdE0/other
nvram=/dev/sdE0/nvram
mouseport=ps2
monitor=vesa
vgasize=1024x768x16

ohh.. that's wierd. I have *msi=1 on the usb plan9.ini. the installer didn't put that into the on-disk one. it put all my other mods in so I didn't think about it.

And that was it! Both problems gone with this one line: *msi=1
