First, HTH congratulations on your 1000th post. Thank you for using it to contribute to my expanding understanding of this topic. And here I was feeling kind of puffed up about reaching 50 (posts that is).

I have a genhd.c patch given to me by squeet modified for LinuxPPC use, but haven't gotten around to installing it. I found myself having problems getting yaboot to accept a SCSI drive as a host for the kernel file. Went through all the steps to find the precise device path and at the end it announced it wouldn't work off a <scsi-2> device. Had to repartition my ATA drive so I'd have a small HFS partition to host the kernel. Still haven't gone to the trouble of compiling in the patch.
Hmm, this is worrisome. I have been trying to get linux installed on a SCSI device. As you may know the G3 has both IDE and SCSI busses. My current configuration is:
IDE 1 Master: the standard MacOS boot disk
IDE 2 Master: the ATAPI CDROM drive
SCSI internal buss contains 4 GB Hard Drive and a 1 GB removable media Jaz Drive
I have the 4 GB HD partioned with 1.5 GB as MacOS 9.0.4 and the rest Linux /root and swap. My thinking is to be able to pull the two IDE devices out and be able to stick two TiVo devices in and have access to them from Linux running off of the SCSI device and to be able to do compressed backups to the MacOS partition for eventual writing out under MacOS. Is this a pipe dream. OBTW, I'm so new at this I don't even know what genhd.c is. From what I've read I assume its the linux kernel code that handle disk IO.

I have accessed the drive myself though. I did a dd conv=swab copy from my backup to another drive, edited the start of the partition map to make it have the Macintosh magic number and block size and suddenly I could access the whole thing directly under LinuxPPC.
Sweat is starting to bead on my brow.

Sounds just like the case I got for mine. $70. Blue-green (depending on lighting) buttons and matching decorative bottom front panel? Both sides come off, motherboard can fold out if you leave out three screws, keep two others loose, and unscrew cards from back plate? (If only the back plate would fold down with the motherboard like in the Blue G3 case.)
Yours is much nicer. Mine has a big one piece wrap over cover that is attached by screws. The MB is screwed to a fixed base plate. But I got the whole thing P-120 MB (will do 166, wee doggies), 48 MB RAM, 2 GB HD, Ethernet, and 56K modem for about $40.

What's the best way to do a multi-boot system? Mine will be starting with just a 48X CD-ROM and a 27.2 GB Maxtor, but I have Windows 98, plan to get some kind of PC Linux, and possibly putting Windows NT 4.0 on it as well (that's what I have to use at work).
As my previous remarks indicate I am not the person to ask. But I think it involves the boot sector on the C: drive and that you want to install Windows before anything else because it is not very well behaved. I'm reading "Using Linux" by Jack Tackette, et al and it has a section on this associated with partitioning. I'll let you know more as soon as I figure it out. Send me your E-mail via PM as this seems a little off topic for this forum.

My two 14hr drives are just for reference, not for upgrade. But I have a spare 45 GB drive I can use (as soon as I'm sure I've recovered as much as possible from it--never hook up two masters on the same bus) to receive a virgin 1.3.0 image. As I have two TiVos and concerns about locking to crypto chips, I'll need to make two backups. Put virgin in TiVo 1, download, reboot to install, shutdown, backup, revirginize, put virgin in TiVo 2, upgrade, download, reboot, shutdown, backup, restore backup 1 to TiVo 1, restore backup 2 to TiVo 2. Sign up for about 80 season passes again between the two of them.
It will be interesting to see what 2.0 has up its sleeve. This is one of the reasons that I thought the Removable HD Racks would be useful. I also want to have 1.3 as a fall back position if I don't like what 2.0 does to my system. But I'm not going to worry about it to much. TiVo as appliance works just fine for me. I have the life time subscription and my wife has no more doubts as to the wisdom of the purchase. TiVo as toy is a separate box down in my office and I'm willing to have TiVo have it's way with the appliance if neccessary.

Swapping out drive pairs though is so inconvenient. Give me a RAM disk (or drive) big enough to hold just partitions 1-9 and make my second drive contain only partitions 10 and 11. By having the second drive contain all the MFS space, both application and otherwise, one should be able to swap just one drive. Requires ability to move primary drive data to another drive and enlarge it or add second MFS partition to it on second drive. Does limit total available capacity per configuration, but avoids multiple Rube Goldberg devices needed to swap drive pairs.
You have thought this through much further then me. The RAM disk is a good idea. One of the biggest down sides of the upgrade is the time that it takes to make changes to the recording and deletion scheduling. Many things take almost 15 seconds to transition. I've been thinking about things like co-processors and overdrives but this is much more then I'm technically capable of at this stage.
Have you done the RAM upgrade? If so, what if any benefit have you noticed?
