Hi Christian, have you tried installing the I350 on a different slot or you have other adapter for further isolation whether it's PC issue (BIOS) or I350 issue?
I have tried as you suggested. What I can say is that neither the same card in a different slot, nor another I350-T2 in whichever slot, work as expected. The behavior is somewhat inconsistent and confusing.
At one point I thought I had found that the long delay and the multiplying UEFI entries only happen when "restart"ing from the OS, booting from full power-off (power supply switch), or entering the UEFI setup, and that neither happens when booting from soft-off, but then I retried and could not reproduce. The difference in behavior was that the time spent in POST code 92 ("PCI bus initialization") was as short as usual, and it spent a few second in 99 ("Super IO initialization") instead. I cycled it five times and ended up with three UEFI entries for the card; five OS "restart"s in a row will result in six such entries. (Sorry for the incoherent info dump, but I don't have a clue what I should be looking for.)
My I350-T2s are both about the same age (manufactured around the middle of 2014). I have another one on order and it should arrive on Tuesday. I will test that one as soon as it gets here.
In case it helps at all, the mainboard is an ASUS Z87-DELUXE, the CPU is an i7-4770K that I wasted a good bit of money on because I'm not overclocking it at all.
(In my opinion, all hardware should be emulated in software, including the hardware the software runs on, but will anyone listen to me?)
Hi Christian, based on the information you've provided. I'd suggest checking with ASUS for possible solution (BIOS-related solutions (update, recovery) since the problem occurs intermittently and in different slots with 2 I350-T2.
yes, I had reluctantly come to the same conclusion. That other I350-T2 will be here tonight, and if it does not work either, as I expect will happen, I will have to look for new hardware. The BIOS is the latest available, and is from 2014, so it is very likely also the last release.
Thanks anyway for your help.
