In case you’re trying to update the firmware on your Intel SSDs by using their handy dandy issdfut Version 3.0.7 or 3.0.8 ISO just to be greeted by an ISOLINUX error like
Failed to load ldlinux.c32
Boot failed: press a key to retry…
Chances are it’s because their ISO seems to be broken when booting using legacy BIOS mode. Switch to UEFI and it will most likely work the way it’s supposed to.
When you’re done, don’t forget to switch back to legacy BIOS if you installed your OS that way, otherwise it probably wont be able to boot.
Having noise issues on your external USB audio interface when connected to a desktop PC and powered studio monitors? Chances are you’re having issues with your grounding… Make sure you are using balanced cables, meaning three wires (two phases + ground) to connect your speakers to the output of your interface.
I recently spent quite a few hours chasing down an extremely annoying crackling hum on my audio setup because of that. No ground loop, all devices connected to the same circuit, I even hooked everything up to an online UPS so I get perfect sine voltage but to no avail. When connected to my main workstation there was a noticeable and extremely annoying background noise on my monitors that wasn’t there when I plugged the Focusrite Scarlett 2i2 into my notebook or mobile phone via an USB OTG adapter. Heck, it wasn’t even there when I plugged it into an HP Z600 workstation that is sitting right beside my main computer, all connected to the same UPS, ethernet switches and whatnot…
Turns out I used unbalanced cables from the Scarlett to the monitors and apparently the MSI X99S mainboard (or maybe the power supply?) in my primary desktop computer has for some reason quite a bit of noise on the ground of the USB bus. Or something like that – I didn’t bother to get an oscilloscope to verify.
Swapping the cables from TS to proper TRS (tip-sleeve “mono” to tip-ring-sleeve “stereo” aka balanced) fixed it and everything sounds perfect, no matter what computer the interface is connected to.
I recently got this puzzling error message on an HP ProLiant Server: 601 – Diskette Controller Error with the system just stopping at the BIOS, no way to enter the maintenance menu or continue booting. Well that’s odd, I though… being a BL460c blade server. All the documentation I could find online suggested it’s a defective floppy drive, or loose cabling… which a blade server doesn’t have.
Ok, so it’s a legacy error message. Maybe the BBWC? Nope. Backplane module then? Nope. The disks? Nah. The fucking SD card module? Not even that… Well, let’s try a system reset them using the DIP switches. Nope. Switching to backup ROM and booting with that one… Doesn’t work either. Well, fuck. Remove all the mezzanine cards – basically the system stripped down to the bare minimum. Still the same error.
About three hours later… Being the only removable part left, I figured I remove the CMOS battery and check it while I’ve it remove. Turns out it’s dead. Replace it with a new CR2032 button cell and voila – system boots again as if nothing happened.
So there you go… 601 – diskette controller error apparently really means: your CMOS battery is dead, better replace it. Even though the documentation says otherwise.
Dear HP: Fuck you. I want those hours of my life back.
