Re: HTTP Boot failed to download NBP file if it is .iso type

[Karunakar P <karunakarp@amiindia.co.in>]

Hi All,

Verified that BDS has been updated to support HTTP RAM disk boot. And able to download SUSE iso (>3 GB) from the HTTP server. But the install stops in middle.

I've checked SUSE iso image could support RAM disk boot or NOT with below steps
	1. Go to "RAM Disk Configuration" form setup browser.
	2. Change the disk memory type to "Reserved"
	3. Choose "Create from file" and select the SUSE iso image from a local USB disk.
	4. After the RAM disk is created, go back to the boot manager, select the new created RAM disk device to boot from it.
 
When I tries to boot from it, installation stops in middle.
Note: Tried with SLE-12-SP2-Server-DVD-x86_64-GM-DVD1.iso

If there anything else I've missed please let me know.
Could you please help which ISO images supports this RAM Disk boot?
Have you verified HTTP boot with any iso image?
 
Thanks,
karunakar

Hi, Naveen

First let's kick out the HTTP and check whether your SUSE iso image could support RAM disk boot:
	1. Go to "RAM Disk Configuration" form in your setup browser.
	2. Change the disk memory type to "Reserved"
	3. Choose "Create from file" and select the SUSE iso image from a local harddisk or USB disk.
	4. After the RAM disk is created, go back to the boot manager, select the new created RAM disk device to boot from it.
If your SUSE iso image could boot in above way, please check whether your BDS has been updated to support HTTP RAM disk boot.


Best Regards,
Siyuan
