A4000 freeze, what SCSI settings do you have in CSPPC for an ACARD 7720UW device?

keropi · 30 August 2006, 14:28

I was wondering what settings to use, right now all is set to auto, but it does not feel too fast, plus doing a SYSINFO DH0 speedtest, it gives 6.5MB/sec... doing a second leads to a reboot...
I have connected to the Acard 7720UW an 80GB WesternDigital IDE drive , acard had termination disabled and I use 2 LVD/SE terminators....
below is a pic, with the CSPPC settings and the different that UNITCONTROL shows... ? also SCSICONFIG complains that the Cyclinder*Heads*Blocks spans more sector than the HD really has
I use the SCSI files found on the Unofficial PowerUp support site...
something is terribly wrong, right?

alewis · 30 August 2006, 16:11

I get the same message (CHB span error) from SCSIConfig, I use HDToolbox from OS3.9 instead.

Set LUNs to 1

Set the Async/Sync selection to Synchronous (its faster, I think I got that round the wrong way in another thread).

Sysinfo also crashes on a rerun here, I think its a bug in Sysinfo, or an issue running it on an 060 (I'm not about to stick the WarpEngine back in to test under an 040). Diskspeed gives much more accurate results anyway)

keropi · 30 August 2006, 17:05

oh, it is good to know...
I will set luns to 1 , and sync the drives.... let's see

Framiga from .org suggests: try to set the unit 1 to Synchron and Reselection (about the speed)

alexh · 30 August 2006, 17:36

AFAIK the CHS method only supports upto 8Gig? You have to use LBA after that?

Bamiga2002 · 30 August 2006, 17:54

I never used UnitControl after i switched from Blizzard 1260 to BPPC, you can adjust the settings in the ppc bootmenu instead. U don't have to use UnitControl or SCSIConfig.

How about using SCSIBench for hd speed tests?

Anyone know why when I access this site using AWeb onthe Miggy, I log in, but when I go to post I'm not logged in?

Anyway, only reason I wanted to was to post my diskspeed "scores".

MUCH better! Between 21mb/sec and 28mb/sec reads with 32kb and 256kb buffer, (and various rates in between, depending on whether using LONG or WORD alignment.

Interestingly enough, no matter what I set in the RDB, MASK remains at 0x7FFFFFE and Max_Trans remains something daft like 0x001E0E, ie only to 24bit ram and small transfer rates... surely this should be able to be set to 32bit RAM, and humungous transfer rates. It isn't a limitation of the NCR875 chipset, nor the Quantum drive.

@alewis:
The CSPPC SCSI controller can DMA to/from byte-aligned addresses - in other words all addresses, as byte is the smallest alignment.

If you dont have the mask for your partitions set to match these capabilities, you will get a big and unecessary performance-hit for addresses that does not match the mask. The correct mask for the CSPPC is 0x7FFFFFFF, which in short means "DMA transfers allowed to/from the first 2GB of addressspace on all alignments". The "7" makes it the first 2GB and is because that is where the Amiga has memory.

For example, the mask 0x7FFFFFFC, will prevent the controller from doing DMA transfers to/from byte- and word-aligned addresses. The "C" means that the two lowest bits are missing from the mask and the result is a no-no for DMA transfers to/from word and byte-aligned addresses.

When an address does not match the mask, the controller will DMA to/from chipmem and use the cpu to copy the data between chipmem the final location in fastmem, which you can understand is very slow.

alewis · 31 August 2006, 00:19

@patrik - cheers, know that (thought I can't remember which mem type F, E, C correspond to, other than F gives better performance), but it won't accept it/stick. Set mask to 0x7FFFFFFF, saved, and on subsequent reboot it is back to E. Similarly, max_trans stays set at some very low setting (I can't give exact settings, as per post above I cant get aweb to keep me logged on abime).

Now if I can get SFS onto DH0:, I can start cooking on gas :-)

patrik · 31 August 2006, 09:50

@alewis:
Are you using the regular HDToolBox? It sounds like the changes are never saved to the rdb, as the rdb will not change by itself. Have you set it for all partitions?

keropi · 31 August 2006, 09:57

Damn... although I lowered the scsi bus mhz , I saw no good... even worst, installed x-arc demo, and on the end of installation I got a reboot... and the corrupted gfx in quake is suspicious too...

alewis · 31 August 2006, 12:16

@Keropi - *dont* lower the SCSI MHz, there is absolutely no need to do that Just change the async/sync to sync. Leave reselection.

alewis · 31 August 2006, 12:20

Yes, as the Phase5 stuff seems to corrupt the RDB...

alewis · 31 August 2006, 12:23

The more I think about it, the more I think this is an Acard/IDE issue. Try a really low max_trans setting, like 64kb (whatever that is in hex)

patrik · 31 August 2006, 12:26

@alewis:
Yeah, the P5 software for partitioning disks is a piece of turd.

Anyhow, I have never had any problems saving the mask when using HDToolBox on any P5 controllers, including the CSPPC.

keropi · 31 August 2006, 13:01

maybe I need to try another HD brand? I have a Maxtor80GB and I ordered a 2.5" 40GB Hitachi HD... I wanna use the 2.5" on the 4000, no space for a 3.5 drive...

patrik · 31 August 2006, 13:34

@keropi:
As I said earlier, there is space for a 3.5" drive. In which way does it not fit?

keropi · 31 August 2006, 13:46

it conflicts with the pci cards metal brackets... anyway, it would be better with a small 2.5" drive, because there would be more space for the HUGE scsi cable... although round , it needs space...
grabbed a 40GB 8MB cache 5400rpm Hitachi 2,5" HD...

patrik · 31 August 2006, 14:36

Ok, weird conflict, should not differ from Zorro3 cards metal brackets.

Regarding the scsi cable, you can cut of a section if there are more connectors than you need. Just cut it clean, straight after the last connector you need on the non-terminated part of the cable.
