Subject: Spry AIR series

I was at interop and stopped by the Spry booth to check out the Air series
applications. They look good at a first glance. Does anyone have any
success or horror stories implementing this package on a Novell 3.1x
network with clients running ODI, LWP (winsock - 4.12), and Windows 3.1 /
3.11?

    I got around this by getting the 2842 Vesa Local Bus, bus
mastering controller.  It does FAST SCSI and is pleasantly quick with a
seagate 3340n fast drive!

_]  I run Windows on a SCSI system with no performance problems whatsoever.

    me too.
_]
_]If you are accessing your SCSI disk via the SCSI BIOS, though, you may
_]indeed have a major performance problem.  For a busmastering SCSI
_]adapter, this implies that you are using the double-buffering function
_]of SMARTDrive, which will turn the fastest system into a dog.

    now we have to talk.  The nice folks at Adaptec said that I do not
need to run an ASPI driver until I go over 2 drives on the SCSI bus or add
a CD-ROM or other removable media device.
    Secrets of Windows 3.1 says that double buffering is needed with
    any bus mastering device unless:
    1) the device does its own on board buffering
    2) the device drivers do their own buffering in RAM
    3) the device driver supports the Windows Virtual DMA protocol.

_]What you desperately need is an ASPI driver that either (a) supports
_]the virtual DMA interface directly, or (b) provides the necessary
_]buffering itself.  This will allow you to get rid of the SMARTDRV
_]/DOUBLE_BUFFER line in your CONFIG.SYS.
    Adaptec docs say to remove the /DOUBLE_BUFFER, set VirtualHDIRQ=off
in system.ini to make everything happy in Windows.

_]Adaptec's ASPI4DOS has a switch to provide the necessary
_]buffering itself
    I have the Adaptec docs here in front of me and there is no
switch to enable buffering in aspi4dos.  Neither do any of the other 3
drivers.  Hummm.

    So...

    The questions to answer (Adaptec's docs do not) are:

    Do the Adaptec drivers support VDMA?
    Do they do there own buffering?
    Is there buffering cache on the ctlr board?

    Anyone know?

Yes, let me second that!  It's frustrating to have to "go" to a site
before the bookmark can be added..... Manual editing of the WSGOPHER.INI
file is a pain.  Am I missing something real simple?
