I still find that SDD works much better then Panorama here on my older install where SMP is broken anyways. Colours are correct under SDL (perhaps a SDL bug) when using 32bit colour, monitor goes to sleep when the screensaver tells it to, by chance the MTRRs seem correct on both. SDD might still be easier to extend and some newer cards may be compatible with the older cards and just need enabling.

of course SDD is much faster than panorama  -  I run SDD + x850  and can tell that this pair is the best choice for os/2 for now

but adding new card to SDD is approximately the same as building new grad driver like panoR200

I tried to make it for my x850 -  unfortunately met  lack of docs

(all above is for 2D only, I have no idea how to use 3D acceleration)

the source of SDD  is not that necessary  as it may seam
to add new card someone has to have tech docs for this card anyway
some time ago i tried to find such docs  -  they are not open

on the other hand the grad driver is not very complicated  itself
having docs it is  better to write a new  driver (like pano R200)  rather than
add cards to SDD

SDD has multi platform design which is obsolete in our case thus we can make
a driver in simpler way

use SDD source to rebuilt it to be SMP friendly   -  is not very good idea too  -  supported cards very old and  almost nobody use them

At some point Bitwise is going to run out of funding for the Firefox port, dmik has put a lot of time in understanding the code, which is a huge mess so I'd suggest it as another use for the fund.

I would support this idea too  -   without proper browser,  os/2 has no chance to survive

Finally got around to testing the newest OS/4 kernel on my Warp V4+latest free fixes install. It hangs when it should go graphical. The new Doscall1.dll did seem to make the system more stable though, it's a somewhat crufty install from '96 or so and crashes if I enable more then one core but runs fine with one core and doesn't have the FPU problems that newer versions of OS/2 have

os/4 is SMP kernel  and  cannot work with UNI doscall1 from Warp V4
you should use dc1 from os/4 package or from Warp 4.5 SMP

interesting to see comport log with that crash

Missed this post until now  :)

I have the SMP kernel and SMP doscall1 as I've tried to enable both cores previously. No comport on this box. Wish there was if only for the modem.

it is hard  to say what is wrong in your case  -  try some other hardware if possible
and do not forget use proper com.sys and other drivers  for SMP

Dariusz,

please  show com port log   -  it may help to understand where is hang

Setup & Installation / Re: Project: Building an OS/4 Merlin DVD

For those interested in: I am trying to build an

bootable OS/4 Merlin DVD with all latest Drivers and QS Loader from Scratch

good idea,  you may also try to use os4apic.psd

2048 will screw up with video cards with lots of memory and probably other hardware setups.

VAL does not have any connection to physical memory

panorama maps 16M only

SNAP could be tuned to map as much as necessary    -   for example "gaoption vidmem 8"  will restrict  memory usage to 8M (I use this setup to save _virtual_ memory on my PC)

Doug, as I recall, 16-bit timer0.sys fail is okay because its function is now fully substituted by the clock03b.sys system driver written by Phoenix.

clock03b.sys contains two drivers:  CLOCK$ and TIMER0$  (having more than one driver per module is allowed in OS/2)

you may remove timer0.sys from your config.sys  or you may leave it as it is   -   a difference will be an appearance  of the error message only

I will try the USB to serial adapter, if I can find it. Meanwhile, I guess I will run the os4krnlr version, to see what else shows up.

USB to serial adapter will not help you  if your test machine does not have com port.

I gave OS/4 a try on my Lenovo ThinkPad L530. It has a 2 core I5 Intel processor, with 4 GB of memory, and UEFI BIOS.

If I try to use the os4krnl file, it always hangs hard (the mouse won't even move) when the blue screen first appears. The next thing that I expect to see, is the STARTUP.CMD window. The only way out is to hold the power switch for 5 seconds.

If I try using the os4krnlr file, it seems to boot okay, but I haven't tried everything yet.

The good news is that it gives me 3170 MB, where the IBM kernel gives me 512 MB.

I find the documentation to be somewhat confusing, and the OS2LDR.INI file is not all that helpful, but experimenting with it doesn't seem to do any damage.   :-\

is it possible to see comport log file ?

try to start without STARTUP.CMD


Well, after a bit more testing, I found that using os4krnlr boots okay, but trying to use UNIMIX.EXE causes a strange problem. It works, as expected, with the base eCS 2.2 beta II install (IBM kernel). If I try it with os4krnlr, UNIMIX.EXE responds with "SYS0193: UNIAUD cannot be run in a OS/2 session." (yes, it does say "UNIAUD"). I am not sure what that is all about, but something is wrong.

I have just check it on my comp   -  UNIMIX.EXE works fine.

Does uniaud work ok with os/4 kernel on you comp ?

I was wondering if this kernel can make use of Hyperthreading?

I have it tested on HT cpu  -  so far, no problem was found.

Also, what does the new screen03.sys driver add?

SCREEN03.SYS is mostly 32bit coded and uses new KEE entry:

KernAllocLDT & KernFreeLDT analog of  DHPhysToUVirt
KernVMProcessToGlobal analog of  DHVMProcessToGlobal
KernVMGlobalToProcess analog of  DHVMGlobalToProcess

KernVMAlloc2 same as  KernVMAlloc but recognizes cache control flags :
   VMDHA_UC
   VMDHA_UCMINUS
   VMDHA_WT
   VMDHA_WP
   VMDHA_WB
   VMDHA_WC

KernVMAlloc2 with VMDHA_WC is called from SCREEN$ IOCTL 80.B -  this way  mapping for Panorama LFB receives Write Combine caching.

Programming / Re: Where do I find hd4disk.add, acpi4.sys ?
« on: January 15, 2014, 06:25:56 pm »
I have read about these drivers but they are not contained in the OS/4 package ?

acpi4.sys is not yet released. Some testers received it for alfa testing.

- when using OS/4 kernel and OS4APIC.PSD the system right at the beginning while booting states that the ACPI4.SYS is missing. Unfortunately the systems allways hangs with this constellation, right before FAT32 drivers are loaded. But if I REM the RUN and IFS for Fat32 it still hang....


can you show comport log of it ?

Forgot to say:
1) I have IBM bootmanager installed as I have 2 OS/2 installations on this machine: 1 for debugging, 1 for normal use, both of which use the SMP kernel (debug and retail respectively). I replaced OS2LDR on the debugging partition.

2) the debugging partition where I tried to run OS/4 kernel is formatted to HPFS

nothing special   -  should work
