CDROM on third drive?

CDROM on third drive?

[kokamoto]

A happy new year!?
really happy?  I doubt it from an old man like me.
For young guyes, A Happy New Year definitely!!

My motherboard has an IDE for DVD and three SATA connectors.
The ATAPI CDROM is recongnized as the forth(3 if 0, 1, 2, 3 drives) by BIOS
which dosen't allow me to rearrange it. So, 9front kernel on that machine dosen't
recongnize IDE DVD drive.

If I want to change the source to change this, which source file I can edit?
Or is it difficult?

Re: [9front] CDROM on third drive?

[cinap_lenrek]

the 9boot loader should have no restriction on the drive
order. it gets the drive number passed in a register when
bios enters the bootsector code.

so, if the kernel got loaded but is unable to access
the dvd drive, then there is something else wrong.

maybe the ide controller isnt recognized or in the wrong
mode. can you enter !rc and cat /dev/sdctl?

Thanks cinap

cat /dev/sdctl says:

sdE ahci ich port 0xffffff000000f200: iss 0 ncs 0 np 1 ghc 80000002 isr 0 pi 3f 0-5 ver 0

My BIOS Main message says:

IDE Channel 3 Master  [ PIONEER DVD-RW DVD-]

I have no HDD drives, but have only one IDE DVD drive.

Re: [9front] CDROM on third drive?

[cinap_lenrek]

it seems plausible that your drive is on this ahci controller,
as the pi shows 6 ahci ports. (if this is physical sata is
a different matter).

try booting with: *ahcidebug=1

just for info, can you check if there is anything in #S?

maybe the sata controller is just slow attaching the
drives so they dont show up in the boot device listing.

Re: [9front] CDROM on third drive?

[cinap_lenrek]

i'd like to see pci information on this. could you, instead of mounting
root from cdrom boot from plan9 fileserver and run pci -v command?

alternatively, run this in the !rc shell:

grep '^01' '#$'/pci/*ctl

another thing would be to look in bios if there is any option for
IDE/AHCI/RAID settings. maybe it does emulate a ide controller that
that is not probed or detected and switching to AHCI mode (if theres
such an option) can make it appear on the sata controller.

		case (0x2828<<16)|0x8086:	/* 82801HBM SATA (ICH8-M) */
...
and recompiled the 9pcf.

Then,
cat /dev/sdctl
-----
sdC ata port F500 ctl F400 irq 11
sdE ahci ich port 0xe0002200: iss 0 ncs 0 np 1 ghc 80000002 isr 0 pi 3f 0-5 ver 0

Now I got sdC line here, however I don't have /dev/sdC0 device.
How I can do it?

My BIOS is Phoenix-AwardBIOS, which has only one option for
IDE related thing.  The below is the menu tree:
Integrated Peripherals
	OnChip IDE Device
		LEGACY Mode Support    [Enabled].

If I choose this option [Disabled], the 9pcf kernel makes panic.

Kenji

Re: [9front] CDROM on third drive?

[cinap_lenrek]

so there is a second ide controller there in legacy mode!
can you make a photo of the panic with legacy mode disabled
and send me your 9pcf kernel?

[kokamoto]

I sent this by personal mail,
because it's too large file.

Kenji

Re: [9front] CDROM on third drive?

[cinap_lenrek]

found it, i made a new kernel under:

http://felloff.net/usr/cinap_lenrek/9pcfkenji2

the problem is that the ahci pci bar is probably wrong.
i added checks for this now so it shouldnt crash in this
place anymore.

if there are still issues, pass the *noahci=1 boot
parameter to the kernel in non-legacy mode. that should
at least get the kernel up and we can inspect the pci
device (using pci(1)) from netbooted plan9.

Re: [9front] CDROM on third drive?

Wao!
Yes, your patch worked very fine.
cat /dev/sdctl says:
sdC ata port F100 ctl F000 irq 11.

When I inserted 9front CDROM,
ls -l /dev/sdC0 says:
--rw-r----- S 0 sys sys 0 Jan 4 11:50 /dev/sdC0/ctl
--rw-r----- S 0 sys sys 5555814000 Jan 4 11:50 /dev/sdC0/data
-lrw------    S 0 sys sys 0 Jan 4 11:50 /dev/sdC0/raw

then mounted CDROM to /n/cdrom, and then
cat /n/cdrom/cfg/plan9.ini says:
# config for initial cd booting
cdboot=yes
mouseport=ask
monitor=ask
vgasize=ask
bootfile=/386/9pcf.

All very good!!

Many debug lines are like:
ataready: dev f100: a0 reset 88 ready 0 ataargs 0xF100: 0x20 0x03 0x00 0x00 0x00 0x51

and cat /dev/sdctl says:

Thank you very much cinap.  You works very fast and fine!

PS.  Your kernel(9pcfkenji2) has much improve of Japanese USB keyboard,
if we can neglect the nonability to input these four characters, '|', '¥', '_', '\'.

Thanks cinap, now I have very cute small 64bit 9front
terminal with C2D(E7400)+4GB memory.
This box was called as Xcube from ASUS (20x20x32cm)
which can use 1 HDD and 1 DVD upto 4GB memory.

I don't like Note's small display and huge desktop boxes.

Kenji,

Running sysinfo -p will post information about your system to sysinfo.9front.org so others can find it later. Its possible to add it to the knownworkinghardware wiki page too.
