UBoot IDE scan
Not too shy to talk
Not too shy to talk


See User information
Since replacing my DVD drive my boot times have decreased substantially. Especially soft reboots as it doesn't hang looking for a there/not there drive. However during the UBoot phase it still scans the IDE chain a couple of times and IIRC isn't there a way to disable the second scan?

Sorry, but that flag has nothing to do with IDE scan performed by UBoot.
It's used to tell SLB to scan the bootsources from the first one instead of the currently used one.

I have my hard drives on an SII0680 card and my CD and DVD on the normal A1 IDE bus.

I did a SETENV IDE_MAXBUS 0 followed by SAVEENV which means that the CD and DVD do not get scanned at all during the initial UBOOT FLB. This speeds up the cold boot time a lot.

The CD and DVD are still seen and are accessible by OS4 so there is no need to scan them at all during UBOOT.

The only time you need to scan them is to BOOT from an OS4 update CD and how many times do you need to do that. It is only a little effort just to scan the CD drives on the few times you may need to.

So is there no way to disable the second scan in UBoot?

I would like to be able to put my SiL card back in the A1, but I already have Catweasel, SCSI, and VIA USB cards populating all the slots. Which brings up another question--if I were to get the fix done and could remove the USB card, would there still be any advantage to using a SiL IDE card?

I use an external powered usb hub instead of a usb card, and my usb works perfectly through that.You could free up one of your pci slots the same way.

No, I can't use an external hub; I've tried. I need a VIA-based USB card to be able to get any sort of USB at all.

The USB can be fixed very cheaply with a few resistors. If you don't mind taking out the motherboard and can use a soldering iron it is easy.

If this is too risky then a cheap USB hub, it doesn't even have to be powered, will also fix the USB problem.

Bootlist? I'm sorry, I don't understand.

From the UBoot main menu choose Boot sequence
then Amiga Multiboot Options
be shure there are no CD in Boot Device 1, 2, 3

Hope this help.

OK, using prefs/UBoot in the Boot sources selection I made sure the First (and only) bootsource is Onboard IDE Disk. This got rid of the second scan, but so there is no way I can set the Second, Third or Fourth bootsource without getting the second IDE scan?

if I remember right the second scan it's made only
if you have a CD on the boot list, this behaviour is
necessary to let you to put the CD in the drive after
the power-on.

Exactly.
When the user enters the menu to change the configuration and put a CD in the drive, the A1 couldn't boot on the CD when there was not this second boot scan.
That's why it was added.
