Good comments. Unfortunately, I've put the system away for now. I feel like we should be live on IRC when I'm testing things so that I don't have to backtrack later. I don't always take notes when there's a failure.
I do plan on re-evaluating the BL3 hack once I've ordered the ultra low dropout regulator, which I think should only dropout 0.2 to 0.3 Volts max, meaning I can take it to 4.7 - 4.8 V. I don't have plans to connect my variable DC supply. if I'm going to desolder wires/components and put it all back together when I'm finished, I just as well wait for the new VRM and do everything at once.
It is a little intimidating doing these tests on my finalised system BL3 system. At one point, all the system hangs caused some damage to my system.ini and I wasted 30 minutes trying to fix that. I think I'll try it again with my spare ALi Panda board. However, I think it best to try other motherboards first. My Daewoo ALi Panda board is finecky. You don't even have control over the ISA bus speed - its always at 7.1-ish MHz. Thus, VLB is a must for it, and thus the tower of sockets!
I think the 46 C was the temp of the VRM, not the CPU. The CPU wasn't even warm to the touch when that 25 mm fan was on.
I am not using an SD-to-IDE adaptor; I don't own one. I am using a SCSI2SD adaptor, version 6. I have a dedicated unit for testing purposes.
It is possible that the BL3 needs a peltier to get a higher speed. Will have to wait for heatsink removal before I can experiment with this. The fact that 3x33 is way more reliable than 2x40 implies to me that there's more at play than just heat, voltage, and operating frequency. My goal is to figure that out, and to do so, I should find another board in my bin which works with the BL3, at least in DOS.
I'm pretty sure I tried the BL3-100 with the L1 disabled and noted it would boot to DOS and run DOOM. DOOM ran so slow, I didn't let it finished and decided to try more settings with L1 enabled.
Plan your life wisely, you'll be dead before you know it.
