AS6102T DOM and BIOS images

[emkeyen]

Hello. I have an odd collection of questions on the AS6102T and AS602 but please bear with me:

1. The AS6102T has 512MB of Flash DOM. How much does the AS602 have? (It's blank on the specs page for AS602)
2. Do they use the same recovery USB disk image?
3. Can I download BIOS updates for AS6102T and upgrade them manually in Debian?

The reason for these questions is that the Flash DOM on my AS6102T is corrupt. It boots fine in Linux on disk or USB though.

When in touch with support, they insist on a recovery USB stick (AS6_RESCUE) that has a 1GB image that transcends the actual flash DOM size and thus makes it unreadable after writing. I think support has mixed up 6xx and 61xx but I could be wrong, hence the questions above. (Also the USB stick does not boot for whatever reason so I followed through the mkFW.sh script manually in Debian, using dd if=firmware/AS-6XX_2.4.0.RFU6.TP2 of=/dev/sdd.)

Regardless, I'm ok with running Debian. My primary concern is getting BIOS updates for the AS6102T for security patches and hardware compability. The current onboard version (v2.23, 06/02/2016) seems unstable and buggy to me.

Here is the firmware from USB recovery stick;

Code: Select all

$ ll firmware/
total 981M
drwxr-xr-x 2 root root 4.0K Aug 28  2012 ./
drwxr-xr-x 5 root root 4.0K Jan  1  1970 ../
-rwxr-xr-x 1 root root   33 Jun 10  2015 AS-6XX_2.4.0.RFU6.MD5*
-rwxr-xr-x 1 root root 980M Jun 10  2015 AS-6XX_2.4.0.RFU6.TP2*

...and here is fdisk of flash DOM after trying to write a 1GB image on a 512MB disk which obviously will not fit;

Code: Select all

$ sudo fdisk -l /dev/sdd

I don't know answers for your questions. However the size of DOM and the size of recovery image are different. That's apparently an error. The only way is to highlight this error to asustor's support to get the correct recovery image.

By the way, BIOS and DOM should be 2 different things. And I believe the upgrade methods are different. Anyway I think you should recover DOM first, then consider BIOS upgrade.

Yeah, that is what I figured. Nice to hear a second opinion. The support rep has already doubled down on this image or a RMA and does not seem to have an interest in sending the right file and resolving the issue. I suspect a misdirected pride thing.

Anybody here from Asustor that could send me the right DOM image for the 61xx series?

I know. I didn't put it very well. My intent was that if I couldn't get the DOM image, at least I would like BIOS updates.
