OK, one more strange issue that came out of my rebuild, as described in this thread.
My beige G3 has a 6.4 gigabyte hard drive, that I believe was probably its original drive; it bears the Apple logo.
In rebeuilding it, I thought I'd use, instead, a 10-gigabyte Western Digital WD100BA60AGA0 drive.
I know about the 8 gigabyte issue with regard to running MacOS X on a beige G3, wherein MacOS X must be installed in a partition that is entirely within the first 8 gigabytes of a drive.
To this end, I partiitioned drive, with the first partition being 7.99 gigabytes, and the second partition being the remainder of the drive. I installed MacOS 9 on the second partition, and learned that the 8 GB limit apparently does not apply to it, as I was able to boot into MacOS 9 frm that partition.
I installed MacOS X 10.2 on the first partition of this drive, which is entirely within the first 8 GB. I noted that the installer takked the second partition with some scary red symbol, and if I selected that partition, it informed me that MacOS X could not be installed there because it was outside the first 8 GB.That is very much as I expected. It did allow me to install in the first partition, which is what I did.
However, I could never boot from that first partition. I'd get a screen ful of the string Can't Load Can't Load Can't Load repeated over and over again, and then, eventually, it'd find the second partition, and boot into MacOS 9 from there. Booted into MacOS 9, I could use the Startup Disk control panel to select that first partition for booting, but I could never actually boot from it.
Other than the 8 GB issue, about which I know, and with which I believe I properly dealt, are there any known issues that pertain to this? In theory, any IDE hard drive ought to work in any computer with an IDE interface, but it seems to me that I have seen something somewhere that indicated that some IDE hard drive shad compatibility issues with some Macintosh models. Might that be the case here?
For the time being, I've gone back to using the 6.4 GB drive.

Just as a followup:Upgrading the ROM from revision A to revision C corrected this problem. I am now happily using my 10G drive as my primary boot device.
