Good afternoon everyone. This is not spam, just passing on a great website I came across. If you go to http://www.freeiPods.com/?r=15699682 you can sign up to get an ipod at no cost. It worked for me. Take it for what it's worth. Tim Sharp

Subject: Re: [q] Micronet SEIV help


I discovered why I was unable to flash the micronet seiv card to an ATTO bios. I'm glad I didn't give up, I almost tossed the card into the trash on several occasions because of all the crashes and lockups it was causing... it was driving me up the wall.

I was entering the wrong hex number for the nubus slot it was in. I kept thinking the slots are numbered 1, 2, and 3. But they aren't. In my Workgroup Server 80, the top slot is 12, middle is 13, and I guess bottom is 14. So when doing a manual bios update to the seiv, I had to enter C as the hex value for the slot it was in (top one). After the update, the crashing and lockups completely stopped and the card is properly detected as an ATTO Silicon Express IV. However, the speed of the card is a LOT slower than it was before. With the micronet bios, during the few times when it ran for a while without crashing, I benchmarked the card at 17.6 MB/s sustained speed with my IBM DPSS-309170 drives. Now, with the ATTO 1.65 bios, and the same hard disks, its only getting 9.6 MB/s. I'm using the ATTO startup item, ATTO A/V control panel, and SiliconExpress control panel. Everything seems to be working fine, but now the speed is ok, but definately not great. 17.6 MB/s was killer for a nubus scsi card, and it wasn't using RAID either. I have the FWB 3.0.2 hard disk driver loaded on the scsi drives. Could the fact that the ATTO bios is not scsi manager 4.3 complient somehow be conflicting with those drivers? slowing the drives down?

--------------------------------------------------------------------------------------------------------------

I recently got a Micronet oem version of the ATTO Silicon Express IV card on
ebay. The Micronet firmware allows the card to be bootable, but is very very
buggy. It causes my 840av to lock up a lot and is driving me up the wall.
Speed on the card is excellent, with 17.6 MB/s transfers, but that speed is
useless if the system keeps crashing.

Anybody know a way to reflash the card to the ATTO firmware? I have the
1.6.5 ATTO firmware update, but when I run it, it cannot find any ATTO cards
(Micronet firmware removes that name). If I tell the ATTO updater to
manually update the nubus slot its in, the updater crashes... ATTO tech
support gave me the cold shoulder and said they don't support old products
like that anymore. I emailed Micronet, but they haven't answered, and I
can't find any firmware updates on their website.

If anybody has any idea's for help, I would appreciate it.


Did you get that from Macguy10 or something similar? I just bought one on Ebay but it won't arrive for several days. I don't recall anything in the item description saying it had Micronet firmware though I might have skimmed over that.

Anyway, if it is the same deal, I will work on a brute force hardware solution and if it works, I'll let you know. Many times these flashers will work if the Flash chip is blank, but not if it has other firmware on board. I can desolder the flash chip, store it's current contents to disk on my EEPROM programmer, erase the chip, and then reinstall the chip to see if the Atto flasher will work on a blank chip. If it won't work on a blank chip, we'll need to see if we can hack the firmware resource out of the Atto Firmware updater.
