There is actually a "hidden" boot picker on these that @LightBulbFun found, but you won't access it by holding "option" as on newer Macs.
Do tell - how does one get to the hidden boot picker?

Boot into Open Firmware and type multi-boot .
Here it is on a Rev. A Bondi iMac(I think all the errors it throws out are a product of the "flakiness" of these early systems-I've not seen a B&W do that). Note at the bottom you're given a list of bootable volumes(only one in this system) and prompted to type a number for the one you want to boot.
Later tray loaders and the Lombard had a primitive GUI type interface for this screen-I'll try to dig that out later if anyone is interested, although it won't be until after I get home from work this evening.

Thank you.
Today I received the ram model 'Kingston KVR133X64C3 / 256 VALUE RAM' and although they are 256MByte, the PM recognize only half of them (128MB). The chips are only on one side.
The B&W G3's are infamous for being very picky about RAM. You need to buy RAM that is tested and certified to work in these towers.
Interesting. So it doesn't manifest in a GUI? It's only in OF?
If I had one of these machines to play around with I'd try it, but alas, I do not![]()
Hmm, maybe I've been lucky on the half dozen or so I have throwing whatever random RAM I have in them(often lowest bidder PC133 LD 256mb from China or whatever I happened to scavenge from the junk pile) or they aren't as picky as claimed...
I think that you were lucky, because myself and many many others have seen how picky they can be. It seems to demand dual sided RAM. The only non-certified stick I ever got to work in mine was a random 128MB from a generic PC shop. And it was dual sided also.

They're not picky, they're just old. It's unreasonable to expect them to work with memory that post dates them by years and intended for other chipsets.
its well known that the G3 BWs MPC106 Memory controller requires the use of Low density RAM, or otherwise the RAM stick will only be seen at half capacity
High density RAM was out well before the B&W was introduced. And the average person will think that anything classed as PC100 will work in a PC100 system. Most don't know to even look past the PC100 spec.
The issue is NOT with high density RAM in general-it is with high density 256mb sticks. All 256mb sticks were expensive enough in 1999 that I doubt many people were buying them, and those that were I would have hoped would have taken the time to research them.
Have you used single sided 128MB sticks successfully in a B&W? I was only ever able to use double sided.
No. They're picky. No other computer I own is that picky with RAM (Or anything else like drives and PCI cards for that matter). They remind me of G5s as those are picky too. My sawtooth is old, and so is my Pentium 120 PackardBell PC. None of these come close to how picky the B&W is.They're not picky, they're just old.

My list of woes when I had a B & W....never again....
1. Rev A 350Mhz B & W working with 192Mb
2. Upgrade RAM - wont boot.
3. Put original RAM back in - wont boot
4. Reseat GPU - boots
5. But then stops booting again
6. Then starts booting again
7. Install OSX but updates won't install
8. Won't verify expanded disk images
9. Doesn't recognise my Firewire optical drive
10. Wont boot
11. Replace HDD with Compact Flash but wont install
12. Replace with standard HDD and it boots/installs
13. Replace CDRW with CD/DVD
14. Wont boot from optical drive unless using commands in Open Firmware
