Hi y'all,
A friend of mine has problems with his Microbotics HardFrame, first some
basics:
He has a rev. 4 B-board.
No, he has a TI and no Signetics bus driver chip.
He has a 1.2 KS ROM and an obese Agnus (1MB) installed.
In addition to his HardFrame (HF) he has an ASDG 8MI board populated with
2MB installed.
The HD attached to his HF is a Rodime 3085S.
Now for his problems:
He get's frequent Gurus and system freezes w/ his setup, the gurus go
away and the freezes get seldom when he removes the 8MI.
If the machine freezes w/o the 8MI, the HD LED is off, but the HF Led
flickers.
The Gurus happen mostly on writes to the HD.
The HF get's rather warm (hot?).
This is his second HF, the older revision he had before was much more stable.
He would also like to know what the 2 new jumpers on the new HF are for.
Another point of grief for him is the MPark behavior:
If you invoke it, the HD won't restart on itself when it's accessed the next
time. If you invoke it a second time = Guru time.
The only way to get the drive back is a reset-binddrivers cycle.
Muchos thanks in advance for any help,
- <CB>

HardFrame jumpers: 1. LED; 2. Autoboot (when set) 3. TIMEOUT (when set (default), 30 seconds timeout, otherwise 5 minutes for the drive to starts; Also, when this jumper isn't set, DEBUG mode activated; 4. & 5. ID# for the HF if you have more than one HardFrame (both set in default, ID# = 7); Also it means drive like Seagate which want to warm up the drive before talking to the HardFrame can be use and autobootable. My experience is the drive doesn't slow down a lot when an overscan image on screen. It does slow down a little bit though. My old OverDrive slow down and it slows down the serial port transfering, but not the HardFrame. And it gets on board buffering to speed up preformance. As AmigaWorld, the HardFrame is what a true SCSI DMA host adaptor should be. Commercial ends. +---------+----------------------------+----------------------------------+ | ///| Morris Y. L.

Hello again, here's an update on my friends HardFrame/8MI problems: He came to my place with the whole shebang and we installed the HF in my system (B2000/A2620/A2090/A2058/KS1.3/Obese Agnus). It worked just fine with none of the mentioned problems showing. However the results of a diskperf we made with a freshly formatted Rodime 3085S made me wonder: File create/delete: create 17 files/sec, delete 52 files/sec Directory scan: 178 entries/sec Seek/read test: 133 seek/reads per second r/w speed: buf 512 bytes, rd 93902 byte/sec, wr 27271 byte/sec r/w speed: buf 4096 bytes, rd 170039 byte/sec, wr 43539 byte/sec r/w speed: buf 8192 bytes, rd 267721 byte/sec, wr 45458 byte/sec r/w speed: buf 32768 bytes, rd 443060 byte/sec, wr 45360 byte/sec r/w speed: buf 131072 bytes, rd 462607 byte/sec, wr 45923 byte/sec r/w speed: buf 524288 bytes, rd 524288 byte/sec, wr 46916 byte/sec I received better results during my HD controller review with the same drive using an A2090 on a 68000 system! As soon as we pluged in the 8MI however, things started to fall apart very fast. A test with Fabian's MemDiag program showed some weak bits on the board. While this still doesn't explain the HF failures w/o the 8MI on my friends system, it least reveals the 8MI (or it's RAM's) as the major trouble-makers. Thanks to all of you who did send in any comments.
