Title: A4000 IDE/Cyberstorm SCSI Boot Scan Time
Post by: adolescent on August 19, 2004, 12:51:30 AM

Any way to speed this up?  I'm not sure which is the true cause but combined they account for ~25 seconds of misery at cold boot.  My A3000 can be booted up and down twice in the same time :-).

Setup:

A4000D
40GB IDE w/SCSIDE on Cyberstorm Mk3 SCSI
Lite-On ATAPI DVD/CD-RW Combo on IDE
Iomega ATAPI Zip 250Mb on IDE

Any ideas?

You do have a IDE drive/dev hooked up right?  I know if you don't the 4000 will sit there and try to look for one for a minute.  Adding one will speed it up.  Are you booting from the SCSI?  Make sure the dev is like 0 or 1 on the SCSI chain, it will boot faster.  There also might be some settings in the CSPPC boot menu?

Hum,
don`t know about the Cyberstorm, but you could perhaps remove (or comment out) BINDDRIVERS- "A command located in the C: directory that is required for non-autoconfig hardware"
from you startup-sequence...that may save `some` time...

@adolescent:

Atleast if you have the newer CyberStorm firmware, you can simply stop scsi.device from being used at boot by setting the "SCSIPatch" option in the boot-menu (I think that was the name for the option atleast). That should stop the A4000 from searching for IDE-drives.

@blobrana

It's not even getting to the startup sequence at this point.  Once it gets through the scan it boots in less than 10 seconds.  

@patrik

Enabling SCSIPatch disables onboard IDE, which I need for my CD-ROM and ZIP drive.  

Anyone else?

If you need the onboard IDE you just have to sit and wait, as the KS looks for Divices with a volume. Maybe you should insert a ZIP-Disk so the IDE will find a device and happyly move along.
You can improve on the SCSI too by setting th units you don't need to O LUNs excluding those units from the scan (and diabeling them for use)

The A4000 always scans its built-in IDE bus.  If you don't have anything connected to it, that's where the delay is coming from.  Either connect something to it, or install the hardware hack to "fool" it into skipping the bus.  I believe the description of the hack is available on Aminet.

@Lemmink

I'll try it with a cartridge in.  I was under the impression that any device on the chain would speed it up, but this doesn't seem to be the case.

@SilvrDrgn

See above.
