ATI Home USB Boot Blank Screen

Thread needs solution

Hey Everyone,

I'm booting a system with a usb hard drive loaded with acronis as described here [http://kb.acronis.com/sites/default/files/content/2006/3/1526/flash-sys…]

I've set vga=ask, and selected almost every available video mode. No matter what I do, I get a blank screen after I select the video mode.

However, the bootable iso cd acronis provides for download works fine.

I have two questions.

1. Is there a way to find out what mode the CD selects so that I may hard set it in the USB syslinux file.

2. Are there any differences between the ISO, and the method described in the solution above such that it would cause the blank screen symptom?

Mark:

The issue you're experiencing may be unrelated to the video mode. The version of Acronis bootable media that you create yourself is different from the version downloaded as an ISO file. The differences are with the Linux loader, and they may also use different versions of the Linux kernel, although I'm not positive of this.

Here is an alternate suggestion. Since the ISO that you downloaded works fine, why not copy it to your USB hard disk and boot it directly? You can do this with Grub4DOS as described in this article:
http://www.themudcrab.com/acronis_grub4dos.php
Look at section 3 for an example of how Grub4DOS can directly boot an ISO image file. However, don't use an ISO that you make yourself using Bootable Media Builder, but rather just use the ISO that you downloaded from Acronis.

Does your monitor have an "info" button/option that displays the resolution information currently being used? Most newer ones do.

You could also try copying the kernel.dat and ramdisk.dat files from the downloaded ISO version to the SYSLINUX hard drive and use them instead of the ones included with TI. (You would probably need an ISO editing program to extract the files. I usually use UltraISO.)

Thanks guys!

Mark, I will try the Grub4DOS option.

Mudcrab, The downloaded ISO I have from acronis doesn't have a kernel.dat or ramdisk.dat. It only has a few files, in the bootable Sector BootCatalog.cat, Acronis.img and then a no emulation img.

Perhaps they're using a different booting method in the ISO they gave you. Have you tried extracting the IMG files and looking at the contents?
