Back to nVidia FX5200

I swapped out the Matrox G550 PCIe card, going back to the nVidia FX5200 PCI card. Main reason would be it is significantly faster and I’ve been spoiled with starting with nVidia cards when I first began working with Amithlon. The nVidia cards seem to have the highest level of hardware accelerated features, besting the Matrox in SysSpeed’s graphics test sometimes 12x faster. Typically it’s 1.x to 2.x faster overall, a few 3x and higher. The Matrox did win a few, I would assume from running on the PCIe bus. The second reason would be Matrox cards are limited to 4mb for Picasso96 while the nVidia card presents 16 mb. This allows higher resolution/higher color depth screen modes.

I am generating SysSpeed “modules” for the cards I’m testing, running 800×600 in 8/16/32 bit color screenmodes. I’ll post the modules soon, adding my A4000T with CyberVision 64/3D as a comparison base.

I’ve used nVidia FX5200 64mb, FX5200 128mb, FX5200 256mb and a FX5500 256mb cards, the 256mb FX5200 showing the fastest results. The 128mb card failed to initialize the framebuffer once loadlin was run (open framebuffer…..no such device) and surprisingly the FX5500 was much slower than the FX5200.

MultiFileSystem (mfs21.lha)

Using the Catweasel and having mountlist for Amiga DD, Amiga HD, PC DD and PC HD, if all were mounted and you put in a floppy….you would have the disk icon for the mounted drive and also, if for example it was an Amiga HD disk, PD1:??, PH1:?? and TD1:?? icons showing.

I installed MultiFileSystem and moved my TD1 and TH1 mountlist into the DF0 folder it created in Devs:DosDrivers.   A reboot brought up a few errors, nothing serious, and low and behold….putting an Amiga HD disk in popped up the icon for it and nothing else.  Doing an “info” showed the mounted volumes….and now it’s DF0: as the mounted name!  So any floppy inserted will show up as DF0:.

The errors I mentioned…..MultiFileSystem scans Devs:DosDrivers and there was a folder for AmigaXL with it’s CD0 mountlist…I just needed to drag that folder over to Storage/DosDrivers so it wouldn’t be mounted.  I had already moved the Amithlon CD0 mountlist to WBStartup as I perfer the CD icon to be mounted after my disk partitions, so the CD icon doesn’t push the partitions out of order if I leave a CD in the drive during boot/reboot.

 

 

Intel PRO-1000 PCIe card installed

Great news, the Intel PRO-1000 Desktop PCIe network card works with Amithlon, Kernel 4.  I pulled my PCI RTL8169 and installed the PCIe Intel Pro-1000 card.  I had already compiled the kernel with the Intel card embedded so booted my system and kept my fingers crossed hoping I’d have connectivity.  The system booted normally (a good sign as the Roadshow boot scripts should have slowed the boot process down as if it failed to connect) and I clicked the icon to launch the shortcut “mount” for my NAS storage box.  Both volumes popped up on my desktop….YES, We have success.  Another PCIe card we can use in Amithlon.  Overall this one seems to be substantially faster than the RTL8169 I was using (both are 10/100/1000 on a gigabit router).  Copying files from my NAS box, downloading files from the internet, all seemed to run faster.

Bad news, the ATI Radeon PCI card failed to work.  I tried 4 different cards with the same results.   I had planned to test both the ATI video and the Intel nic, luckily we have success with one.

Catweasel installed and it’s awesome.

The Catweasel is in and this thing is pretty freakin’ cool!

Unplugged the floppy cable from the motherboard and plugged the end into the black connector on the Catweasel.  I then Plugged the included white cable into my motherboard’s floppy connector and then into the white connector on the Catweasel. Plugged the Catweasel into an available PCI slot.   Using the standard PC floppy drive I already had in my Amithlon system.

With just openpci.library (2.1) in LIBS: and multidisk.device (3.65) in DEVS:, along with two mountlist created, TD1: (Amiga DD disks) and TH1: (Amiga HD disks), I can now read/write Amiga DD and Amiga HD formatted floppies 🙂

I have a few commercial software disk (Amiga DD) so I inserted one and the disk info appeared, double clicked and was able to access the content. I didn’t have any Amiga HD formatted floppies lying around so I grabbed an HD floppy, put it in my A4000T (which has an HD floppy drive) and formatted the floppy. I then moved it over to my Amithlon and it’s icon appeared. Opened it up, dragged file to it and when completed I put the disk back in my A4000T and was able to open the file.

Formats supported (and will require the appropriate mountlist and testing) are:

0 Amiga DD 880 Kbytes double-sided
1 Amiga HD 1760 Kbytes double-sided
2 MS-DOS DD 720 Kbytes double-sided
3 MS-DOS HD 1440 Kbytes double-sided
4 Atari 10 sector 800 Kbytes double-sided
5 Atari 11 sector 880 Kbytes double-sided
6 Commodore 1581 800 Kbytes double-sided
7 XTRA high density 2380 Kbytes double-sided
8 MS-DOS HD 20 sector 1600 Kbytes double-sided
9 Macintosh DD 800 Kbytes double-sided
10 Macintosh DD 400 Kbytes single-sided

The number on the left is the “flag” used in the mountlist to tell it what disk type you are using.

Using this named TH1:  (for HD disk)

/* multidisk filesystem entry
*
* This mounts a logical device on catweasel unit 0 for reading and
* writing Amiga HD Disks. Create mountlists for other units
* by changing the number behind ‘UNIT = ‘ to 0, 1 or 2.
*/

Device = multidisk.device
Unit = 1
Flags = 1 /* format #1 = Amiga HD */
Surfaces = 2
BlocksPerTrack = 22
Reserved = 2
mask = 0x7ffffffc
MaxTransfer = 0x00200000
Interleave = 0
LowCyl = 0
HighCyl = 79
Buffers = 5
BufMemType = 1
StackSize = 4096
Priority = 5
GlobVec = -1
ACTIVATE = 1

and this one called TD1: (for DD disk)

/* multidisk filesystem entry
*
* This mounts a logical device on catweasel unit 0 for reading and
* writing Amiga DD Disks. Create mountlists for other units
* by changing the number behind ‘UNIT = ‘ to 0, 1 or 2.
*/

Device = multidisk.device
Unit = 1
Flags = 0 /* format #0 = Amiga DD */

Reserved = 2
mask = 0x7ffffffc

A PCIe video card successfully tested

I read that Pedro Cotter was using a PCIe Matro G550 card in his Amithlon system so I decided to test one out.  I had removed all the additional framebuffer drivers from my kernel so I did a quick compile of a new one re-adding the Matrox framebuffer and ATI Radeon framebuffer (that one will be tested next).  I removed the nVidia FX 5200 64MB PCI card and installed the Matrox G550 32MB PCIe card.   Powered on (I had already swapped out the kernel on my DOS boot partition and edited the “small” file to reference it), and it booted just fine to my Workbench.  Went in to Picasso96Mode prefs and selected the Matrox-1 card as the board in Picasso96Mode.  Rebooted and all continued to work though I lost a few hi-res hi-color modes, 1650×1080 @ 32 bit and 1280×1024 @ 32 bit, leaving on the 8 bit and 16 bit modes of those resolutions.  I use my own defined 1280×720 @ 32bit so no worries.   The reason is the lower amount of available memory the Matrox framebuffer allows, only 4 MB versus the 16 MB you get out of an nVidia card.  I had to recreate a 320×240 mode as the one I created for my nVidia card threw an “input signal out of sync” on my monitor(s).  Did some regular use testing and didn’t feel much difference, and did some benchmark testing which showed a significant reduction in most test.  A few scored higher, but on average most were slower, some significantly slower.  I attribute this to those functions being tested were not hardware assisted.  I believe nVidia has the highest amount of hardware accelerated functions enabled which gives it a performance advantage.

In real use I’m not sure it’s something you’ll notice that much if at all.  Windows still open and move without feeling different, games still are fast enough.  Simple Quake timedemo demo1 showed less framerate than the nVidia card, but it was still smooth and above 30 fps at 1024 x 768 @ 16bit.

This opens up a PCI slot for the Catweasel (yay) and gives more options for new(er) motherboard choices with supported chipsets, as a lot of the latest ones typically only had two PCI slots (Video and Networking or Video and Audio) and a few PCIe slots.   Now you can have PCI Audio and Networking and PCIe Hardware Accelerated Video.

I plan to run benchmarks in SysSpeed for each video card and save the results as a module and make them available for download as well as displaying the overall results.

Catweasel Mk4 PCI

Picking up a Catweasel Mk4 PCI card, hoping this will work well with Amithlon allowing me to read/write Amiga formatted floppies. The device allows reading/writing Amiga DD/HD, PC DD/HD and Mac formatted disk with a standard PC floppy drive.

The fun part…I’m out of PCI slots. So I need to see if my PCI-e to PCI adapter for my motherboard works or perhaps try a PCI-e network card in place of the PCI one I’m using.

This will be interesting….

And….

The Catweasel is installed! Multidisk.device copied to devs: and I created two mountlist, one for Amiga DD disk and one for Amiga HD disk. Double clicked the DD one and then inserted an Amiga DD disk and its icon popped up on my Workbench. Double clicked it and it opened the contents of the disk. I removed the floppy and the disk icon went away……only to be replaced by that familiar Amiga disk drive clicking.

Any noclick tools work with multidisk.device? – Yes, the Multidisk prefs program from the Catweasel 2 software.  No click enabled….. no clicking.  Bonus, the Catweasel 2 software also included a patch for CrossDOSFileSystem that makes it work with multidisk.device and supports disk changes (no diskchange ph0: or ph1:).
