Ask ATI/AMD Radeon Xpress 200M - also 200/200P - Chipsets' SouthBridge (and their support enhancement)

Ahoy devs !

           Regarding to my ticket (#18076)

I’ve taken some investigations related to applied chipset in the affected mobile laptop machine which is

ATI/AMD Radeon Xpress 200M

and concluded that both

boot issues of graphics and USB detection
running Haiku USB subsystem issues

relates to the chipset - from my point of view.
Also clarified this bug/missing support affects more users than me myself and @zuMI who also reported
in my ticket.

Summarized : that was opened about my FUJITSU SIEMENS Amilo Li 1720 Laptop but should be
modify to a general issue related to ATI/AMD Radeon Xpress 200M/200/200P Chipset versions.

In my case there is

one hand boot issues regarding

¤ Radeon Xpress 200 Chipset/Graphic card support missing :

  even boot from DVD (IDE/ATAPI interface) succeed ONLY 
  as if **'Safe video'**    boot option have selected !

¤ USB subsystem detection fails (BIOS firmware, 32bit) :

USB thumbdrive boot fails - machine diagnose of boot checks
NEVER ENDS and stacks at USB devices checks
until Haiku USB install media plugged in
and had not stopped by force:
using power button to shut down from boot process
and remove Haiku USB thumbdrive install media.

other hand USB subsystem issues

As if boot from DVD succeed(IDE/ATAPI interface),  

then the USB subsystem contains


    in output of listdev or listusb commands.

Such chipset and its several versions works 
    in wider variety of mobile and desktop machines.

As the ticket was opened by me 
  • as it was mentioned always on forum -,
    and logs, outputs were added as well … I’ve expected I get answers
    first to questions in the ticket description
    and later to the last supplemental about my investigation and my last 2 question.

I had not seen answer what @korli asked about PCI stuff – however I do not see direct relation I hoped it might help to someone goes further :slight_smile:

I accept that our HW is old and there is more focus on more modern machines, but as I wrote above – more Intel and AMD machines affected as such chipsets used for longer period and several CPUs but with same or similar Graphics, Sound and USB solution - both mobile and desktop PCs.
Recently I saw more forum posts about similar issues
some might relates to these chipsets and not UEFI/BIOS settings/configurations only.

Thank you in advance
if someone of you checks
mostly USB subsystem related issues,
and maybe Graphics issues (as Radeon as I knew/learned from writings : AMD is more supportive related the docs and engineers as well)

… and at least answer questions in the ticket. :wink:


I have on board (laptop) ATI/AMD Radeon Xpress 200M. Unfortunately, the system boots only in the “Use fail-safe graphics driver” mode.

Dear @Dobro,

Thank you for your report that confirm half of my symptoms with same chipset.

Then the questions are the followings :

Q1 : had you have the same problem with USB booting ?

  I mean, boot from USB thumbrive, CD, Disk : fails or not ?

Q2 : had you experienced problem after desktop reached – no plugged USB devices present ?

Is there any USB device available in Haiku after you reached desktop ?

Honestly, for me, the USB subsystem problems are more important, as not just boot issue, but after I could boot via DVD with IDE/ATAPI interface, no any USB device available/usable.
It prevents/blocks more options : for example install onto external device, or use wireless mouse/keyboard.

Thanks for your answer here
update in my ticket above (#18076): - adding your

  1. syslog
  2. output of listusb -v command
  3. output of listdev command
    to it.

You can copy file and save output to inner disk partition. If other OS also present in there you can give those to the ticket from that - just as I did some other cases. If you have working Internet access, as I had in this case then you can add them from Haiku using Webpositive and registered user in Haiku TRAC ticketing.system ( ).

No. I didn’t have any of the problems you listed above. Although the laptop is quite old.

Just a reminder: You actually can copy & paste text from Terminal… :slight_smile:


Dear @Dobro,

I see, you have the newer version SB600 as SouthBridge, not SB450 as for me and others possibly.

This way you are affected only in case of Graphic Video issue in the NorthBridge part

RC4XX/RS4XX - PCI Bridge (int gfx)
RS482M - Mobility Radeon Xpress 200 (Display controller)

Also I’ve seen the plugged in USB storage device - so it is really different from my case.

Okay, so this way I cannot hope in wider affection due to the same issue for different SouthBridges - so weighing my issue in front of devs
Right, anyway I accept this way USB situation might be specific for SB450 SouthBridge version.

Thanks for your answer -

But still not drag’n drop!
From and to the terminal!

Dropping text into Terminal works. If you think drag&dropping text from Terminal is useful, file a ticket and it may get implemented. Otherwise you will “still” be waiting for a never requested feature.


Ooops … when I saw a number of new posts at this thread and started to hope
finally someone answered my questions of my ticket …
… turns out : it was just another curve of another stuff which does not relate to the title or content of this topic!..

How lame me myself !.. :smiley: :smiley: :smiley:

At least another ticket#8002seems can be closed about SB600 USB issue after my forum post.
There was opened about this SouthBridge issue and now – probed with new hrev – there is no USB timing errors in provided syslog. Only detected USB hardware there - good news.
I have hope in similar outcome in my case - SB450 SouthBridge.

Ahoy again !

I repeat my questions here from my ticket – #18076 – hoping someone would answer them :

From ticket description :

Chipset of FUJITSU AMILO LI 1720 laptop is

ATI (AMD) RADEON Xpress 200M (RC410M) + ATI (AMD) SB450

Question Nr01 :

Could you confirm that missing driver for this chipset cause the problem with USB boot ?

Question Nr02 :

If so - can it be fixed to be able to boot later via USB option ?

From note 17th of the ticket :

Question #1 : Is ATI/AMD SouthBridge SB450 has a proper driver support in Haiku ?

I do not know how the earlier note of korli about PCI issue relates to this USB subsystem issue, but

Question #2 : Could you confirm that - for me -
Haiku does not need chipset driver to support USB subsystem properly ?

And finally the last one … as the bootloader surely does not support the USB subsystem
via this ATI/AMD Chipset - with SB450 SouthBridge -

Question #3 : Can we – who has the same chipset in different laptops –
expect to get an RCA from someone who would investigate
why Haiku bootloader fails to detect USB subsystem
in case ATI Radeon Xpress 200M Chipset ?

Thanks in advance for your answers -

Kind regards,

There are usually no specific drivers at all for chipsets. Nowadays everything is very standard. USB has only 4 drivers: OHCI and UHCI for USB1, EHCI for USB2, and XHCI for USB3. All PC computers use one of these.

For hard disks it’s the same: all modern hardware uses AHCI which is a standard way to access SATA disks, or possibly NVME for even newer systems. Again, this is a single driver for all devices.

However, things are different for older hardware. The Radeon Xpress 200M is quite bad in that aspect. Nothing works as it should, the SATA interface is not compatible with AHCI, the USB implementation is a bit broken, etc. I know, because I own a laptop using this chipset. I have quickly given up on getting Haiku to run on it. I feel no need to spend weeks or months of work on such old hardware. My advice is to get somethign newer and less broken.

Dear Adrien,

Thanks for your answer - it’s finally pour crystal clear water into the glass, as it said by our saying.
This way for such laptops there are no other alternative but Linux – if Microsoft abandoned / killed supported Windows version on them.

Unfortunately it is not accidental I try to install Haiku on old laptops - I own those actually and no hope for modernize … financially.
Besides of material difficulties, so every day needs … I wanted to give a second life to these machines as well.

Against it - I am going to follow how Haiku goes toward R1 :smiley: and beyond :wink:
