[9fans] install kernel fails to find hard disk

[John Stalker]

I just tried to install plan9 on a machine at work.  At partdisk
it tells me

  The following disk devices were found.

  sdD0 - TEAC DVD+RW DV-W58E D.0C09/14/03

  Disk to partition (sdD0)[sdD0]:

No mention of the hard disk.  Typing sdC0 at the prompt doesn't help.
Neither does turning off DMA.

The relevant hardware, as found by NetBSD, is

Perhaps your SATA controller isn't recognised by Plan 9?  sdata.c
contains

		case (0x24DB<<16)|0x8086:	/* 82801EB (ICH5) */

but perhaps yours has a different did (device id)?  What's lspci (or
equivalent on netbsd) list as vid & did for it?

Re: [9fans] install kernel fails to find hard disk

[John Stalker]

The relevant part of the output of scanpci is

pci bus 0x0000 cardnum 0x1f function 0x02: vendor 0x8086 device 0x24d1
 Intel Corp. 82801EB (ICH5) SATA Controller

The vendor id matches, but the value in sdata.c is 0x24DB.  It seems
geoff is right.  I can try to build a new kernel on another machine
to test this.  Is there an rc script or mkfile to build an install
iso, or do I have to do everything by hand?

[John Stalker]

I tried adding 0x24D1 in sdata.c, recompiling cddisk, burning an
install disk, and booting from it.  Possibly I screwed something
up, but I still don't see sdC0.  Is there something else I should
try, or should I give up and run it as domU in xen?

Re: [9fans] install kernel fails to find hard disk

[geoff]

It sounds like you've done the right thing (though I haven't tried
rebuilding the install machinery).  I don't think you should have to
make a similar change to /sys/src/boot/pc/sdata.c until the
installation is done.
