ATTO Silicon Express IV

[Lindon...@hotmail.com]

I just purchased an ATTO Silicon Express IV NuBus based SCSI
controller to use with my Power Macintosh 8100/110. I have the card in
the machine and attached to a hard disk.

•The controller mounts the hard disk on the desktop.
•All drives are terminated and recognized by the OS.

The problem is however I can't boot from the hard disk attached to the
ATTO card! I still have an ancient hard disk attached to the even more
ancient onboard SCSI in which I boot from; and it's very slow.

Does anyone have any experience with ATTO cards? I am aware of this
website: http://www.fenestrated.net/~macman/stuff/SiliconExpress/ and
have downloaded all the files but I still can't boot from the ATTO
card.


I'm wanting to use this fantastic Power Mac as a fax machine/
answering machine with the GeoPort Telecom adapter rather than
spending $2,999 for a comparable machine to recieve 50-200 faxes a day
and I need a high speed SCSI option to deal with storing all the
documents.

You couldn't swap the drives could you? i.e. put the external drive
inside and the internal drive outside. I did that with a 2 GB SCSI
hard drive to minimize noise and it worked just fine. Just had to
remove the drive from the external case and swap them out.

Good Luck,

From my understanding you needed a beta firmware upgrade to make the
card bootable. I have a few SEIV in use but they are all for A/V
drives not the bootable OS HD.

The FWB Nubus jackhammers are bootable.

You were correct! I updated the ATTO card's ROM with the flasher utility to
version 2.1 and it became bootable. Supposidly the 2.1 version ROM update
turns the card into a Macintosh SCSI manager 4.3 card allowing the
Macintosh's SCSI ROM's to interact with the card nativly. The ATTO card is
fast! I was benchmarking the card with a Seagate Cheetah 9.1 GByte wide hard
disk and pulling around 13 MBytes/ Sec; pretty good for a NuBus based
machine.
