There isnt a lot of solid information around on getting HTML5 KVM on the Supermicro A1SRi-2758F boards (to get rid of the horrible Java KVM). But for anyone wanting to do the same, I can confirm that you can use the BMC firmware "REDFISH_X10_377.zip" from Supermicros site to update the BMC on A1SRi-2758F to get HTML5 KVMs. It isnt specifically listed as a working combination anywhere but there was enough evidence that I gave it a try and it worked.
