Q: Mac Pro startup - full chime, then 4 brief ones. Help?
Hello, sorry in advance for the long post, but I want to be concise.
I own a Mac Pro 1,1 which has started to exhibit some strange behaviour. Namely, when the Power On Self-Test runs (meaning I just stated my Mac from full shutdown), I hear the full chime, and then 4 brief ones.
I think that means I get 4 "beeps":
4 beeps = no good boot images in the boot ROM (and/or bad sys config block)
Unfortunately, the article doesn't suggest any way in I might rectify this issue.
Cause or coincidence, but the other day I installed an OCZ Petrol SSD (with Icy Dock) at around the same time this began. However, I tend to leave my Mac Pro on for extended periods of time, so this may have started earlier. I have removed it and tried to use my usual HD, but no difference there.
To date, I have verified/repaired disks and permissions, and both reset the PRAM and the SMC. I used Rember to test the RAM, and TechTool Deluxe 3.1.3 (not boot from disc) to test everything else (it crashes when testing Video RAM). Everything checks. I still have the original ATI X1900T kicking around somewhere.
I would love to run Apple Hardware Test, but I don't have the discs that came with the system. I tried seeing if it'd run from Lion internet recovery, but all I got the first time was a blank grey screen that never amounted to anything, and thereafter it would just boot the system normally.
Trying to boot any DVD other than my Lion disc (burnt in Disk Utility from InstallESD.dmg) gave me a circle with a line crossing it. This includes TTD, Snow Leopard and Leopard.
Here are my current specs:
Mac Pro 1,1:
- Mac OS X Lion 10.7.3 (11D50b)
- 2 x 2.66 GHz Dual-Core Intel Xeon
- 8 GB 667 MHz DDR2 FB-DIMM (4x1GB original from Apple, 2x2GB from Crucial)
- ATI Radeon HD 5770 1024 MB
- MCE 12x Blu-ray Disc Internal Recordable Drive
- Pioneer DVD-RW DVR-112D (original from Apple, bay 2)
- OCZ Petrol 128GB 2.5IN SATA3 Indilinx Everest SSD (enclosed with Icy Dock MB882-SP-1S-1B)
- Drobo (2nd gen), connected via USB (Firewire has proven very problematic with Lion, despite all updates)
It seems, besides loading older OS discs (never tried before) and the 4 chimes, everything is working as usual.
What can I do to fix this?
Thanks,
Jonathan

The multiple chiming thing with added periphials was a problem that was posted some time ago. I don't remember if there was a solution or not.
I don't have that thread handy so you would have to fish around with google to see if you can stumble upon the right keywords to find it (hint, add site:discussions.apple.com in a google search to limit the searches to just these apple discussions).
I don't use Lion so I won't comment on it's problems in this thread's context.
