When I'm reading japanese documentation on υPD765 FDC chip, I found
this chip requires response from the CPU within a relatively short time
period, such that 14υS.  If there is no such response from the CPU,
it goes to overrun error.  Does the Plan 9 DMA mechanism can satisfy
this demand?

Well,... I'm still here (too much anxious to leave from here).

I suspected this Toshiba machine may use NEC's υPD765 FDC, and got a
document on this chip from net 
(http://www.htl-steyr.ac.st/_morg/pcinfo/hardware/interrupts/hard0001.html),
 and found a command (just 0x10) to check what is the name of this FDC chip 
which works only for these NEC's υPD765 families.

Then, I tested this, and got the FDC of this Toshiba Tecra 720 is NEC's 
υPD765A or υPD765A-2.  This means that we have no means to control 
floppy motor rotation speed from this chip, which should be there outside 
the chip.  However, I may not be facing this problem now(I'm not sure).

The document says this FDC chip is not different from the coded one in
/sys/src/9/pc/devfloppy.c where I cannot find any problem sofar.
In fact, commands are sent safely to FDC, and I get right results other
than floppyxfer() which uses DMA transfer.

Are there any recommendation to check if this is just the problem
whichi I'm facing.

Anyway, the document says "INT 6 sets bit 7 of BIOS Data Area location 40:3E
which can be polled for completion status."  Is this also right for Plan 9 kernel?

Re: [9fans] Toshiba Tecra 720 (notebook)

[okamoto]

I'm still having trouble with this notebook's floppy drive.
Linux booting floppy tells me this machine has "8272A" FDC.

Does any other machine with this FDC is working?

I consumed up all the holiday free time now for this floppy problem,
I have to return to my job from tomorrow...

[okamoto]

Sorry, I forgot most important one.

This info is made available by kasukawa@ics.es.osaka-u.ac.jp.

If you need to read Japanese README, please let me know it.
However, I suppose you can guess it from the patching sources to
linux 2.2.x kernel...

Please forget my previous info on changing rotation speed of 3mode floppy.
I tried it, and got meserable result. ☺  It varies model by model.  I attached
more complete info on this.

Re: [9fans] Toshiba Tecra 720 (notebook)

[okamoto]

[-- Attachment #1: Type: text/plain, Size: 605 bytes --]

Sorry I made mistake to attach a file. Once again.

I found a patch to this Dynabook notebook's 3mode floppy for linux
of some version (it's not so important because we know what is neccessary
to set it up).  That is from sengoku@sdl.hitachi.co.jp, and is included
(sorry for Japanese). I'll do this from now.

For someone who does not read Japanese, here is my short comment.
His post consists of two part, the former is not so proper, because it
causes serious speed down to linux.  The latter half is the patch for it.
We are Plan 9 users, so we may have some other effects.  :-)

I found a patch to this Dynabook notebook's 3mode floppy for linux
of some version (it's not so important because we know what is neccessary
to set it up).  That is from sengoku@sdl.hitachi.co.jp, and is included
(sorry for Japanese). I'll do this from now.

I tried to figure out it during this new year vacation, and failed.  At first, I tried to see it
on the working kernel itself what's going on here.

The devfloppy.c reports me as follows when I dispatched a: command:

sra ff srb ff dor ff

I think this error messages say we need some trick to change the controller mode from something
wrong (probably 5¼HD format 6 rotations/sec) to 3½HD (5 rotations/sec).  But I don't know the
command for this purpose.  I don't even knwo what kind of controller chip is used on my Tecra
720 notebook...

Then, I tried to check the floppy.c file of Linux, and found there is nothing for such codes which
means Linux cann't boot itself on this machine, too.   I was much surprised to find this. :-)

Then, I also checked NEC's PC98 codes, and found something such control seruence, and tried it
on my notebook which lead me to the miserable state.  NEC's PC98 has 3½HD, 3½DD and 5¼HD
format as 3½ floppy format.  It seems to do some trick (mode_set), however, it's controller chip
(7072A)may be different from mine.  Therefore, I'm now thinking that we cannot use those notebook's
floppy drive unless we could get some information neccessary for this trick.

Re: [9fans] Toshiba Tecra 720 (notebook)

[Deztroyer-a1]

I think Toshiba's floppy drive for notebook will not run properly under
normal circumstance in the third edition. Because what happened is that I've
attempted to install plan 9 on Toshiba's satellite series notebook (on 2
different models), and Plan 9 doesn't seem like the floppy drive at all.

I think we gotta do some configuration on the kernel or something to get it
work.

Good Luck
Alex

I got 1024x768x8 display for my Toshiba Tecra 720CT notebook.

Used vga controller is hiqvideo, and the /lib/vgadb around there is like:

ctlr
	0xC0090="CHIPS 65550 PCI & VL Accelerated VGA BIOS"	# NEC Versa 6030X/6200MX
	0xC0090="CHIPS 6X554 PCI Accelerated VGA BIOS"	# Digital HiNote Ultra 2000
	0xC0090="CHIPS 69000 PCI Accelerated VGA BIOS"	# Rackmount
	0xC0090="TOSHIBA Video BIOS V2.30"				# Toshiba Tecra 720CT
	link=vga
	ctlr=hiqvideo linear=1
	hwgc=hiqvideohwgc

and added monitor section as:

#
# XGA (Laptop).
#
xga = 1024x768
	include=1024x768
xga
	alias=svga
#

#Tecra 720
#
tecra = 1024x768
	include=1024x768@60Hz
tecra
	alias=svga
#
# LCD
# Just a convenience, really.
#

Yes, 1024x768@60Hz worked fine.

Now I can come home soon, because I don't harry about FDD problem.
I have CD-ROM drive in this notebook.  :-)

Yeah, I'm now in the office just because of this reason.
I'm using hiqvideo driver for this machine, which works partially. :-)
I can run rio only VGA mode.  When I tried 1024x768, it shows acme
windows but not clearly.  There is many noises, and finally it desappears.
I have to read this source from now.  To check graphic chips, we need
another machine to recover from its failure. :-)

I suppose Toshiba (probably also other companies such as NEC etc.) sells 
different models in Japan or in US or Europe.
Then, my Tecra 720CT is not the same as that in your country, particularly
FDD drive.  Once upon a time, the 5" 2HD format was a defact standard
also for 3.5" floppy drive, because NEC used it for their major PC.
After PC got its status also in Japan, we have two kinds of 2HD format
in 3.5" FD drive, one is from 5" 2HD (1.2MB) and the other is from IBM
PC (1.4MB).  I'll check linux sources around this, although I have only
Linux for sparc in home. :-)

Re: [9fans] Toshiba Tecra 720 (notebook)

[Russ Cox]

The error messages say basically that we
don't know anything about this drive and
all reads from it are failing.  

It's likely that these floppy drives are
not quite the same as normal ones.  Does
the drive work under Linux or a BSD?

I had a bunch of Tecras running second
edition three years ago without a problem,
but perhaps they've changed the hardware 
around a bit since then.

Since you've found a way around using the 
floppy disk, I'd worry more about the VGA,
which looks like it should work.

It may be better to describe a part of error messages when I changed
chatty to 1 in dosboot.c, which are as folllows:

[9fans] Toshiba Tecra 720 (notebook)

[okamoto]

I'm now struggling against Toshiba notebook( really!?, it's too heavy to me)
Tecra 720CT, which has 1024x768x256K colors CT56650 graphic chip.
I got this machine for my happy hacking of Plan 9 for this new year vacation.
Upto now, it's not so happy...because it has problem in floppy drive and 
graphic chip and so on.

I'd like to hear about this machine, if someone else has done it.


I'm now constructing kfs on this machine from our network, and it may be 
going good, at least notebook's hard disk is working to write something 
now. :-)

This Toshiba's notebook has external three mode floppy drive, which is 
different from PC's three mode, but it domestic one.  It is three mode of 
720KB, 1.2MB and 1.44MB.  The middle is for old domestin NEC machine 
which is once the most major PC in Japan.   The problem I'm suffering now 
may be more common to many of Japanese Plan 9 users, particularly 
notebook users (because we cannot change the drive!).


When I try to boot from floppy, it fails at reading plan9.ini file.

The error messages I got (by setting chatty=1 in dosboot.c file) are too much
volume to me, and essentially, it says cann't read floppy drive.
After I booted this machine from network, I can't mount this floppy.

This is the first problem.   The second concerns with graphic chip, however,
it's not so serious now, because I'm doing now as VGA, yes, small window. :-)
