SCSI on a G4 Sawtooth

Hello everyone,

I have a ton of SCSI 160 and 320 cards and HDDs from dell servers. Would the cards work in my G4 tower? If so OS 9.2 work or would i need OS X? I don't know how picky they are hardware wise. I have various 32bit and 64bit PCI cards.

Thanks!

They may. But I don't think the G4 would boot from them. scratch that, I doubt it would. Mainly as there has to be a ROM on it.

Howerver, since I had an Adaptec with a PC ROM on it that was pulled from a Gateway machine. It seemed to be recognized by OS X, it just wouldn't boot from it.

Reading and writing from the SCSI Drive was not an issue though. It was able to store data, and had no errors.

I would say, if there was a chipset equivalent on a mac card, I am betting a PC Card sharing the same SCSI Chipset would work.

Go ahead and try it.

Hmmm, the have ROM and RAM but i don't know if the MAC would read it right. They are Adaptec and Promise raid cards, maybe a re-flashing? I will have to play with it.

As far as I know, no promise cards can be made bootable. Adaptec cards have a slight-chance of being made bootable.

One of the main issues with flashing from PC to mac is the size of the ROM on the card. If it's below a certain size, the only way you can get it working if someone reverse-engineers the ROM and rewrites it and some how makes it smaller.

However, if you have the appropriate sized rom, go for it! I think you can flash it in a MAC using adaptec's utilities, but you may have better luck doing it with a PC due to not really being anything keeping you from doing it.

Adaptec made more money on the Mac SCSI Cards because they could charge more since it was a Niche market. One thing they did was kept their utility from flashing PC cards. So if someone has figured out how to get an adaptec ROM utility to flash ROMs without looking at the type of card, you will have luck.

It's just much more dead easier to flash it from a PC under DOS or something.

Go ahead and give us a try. However if you do, try to list the Revision of the card, Model number, and the chipset so we can do it ourselves (or have knowledge). I would be interested to see which cards you can flash from PC to Mac!

If i get a chance i will try after work and post my findings. I have a whole lot of different cards, some simple scsi, some RAID with 128MB ram, daughter cards, batteries, and heat sinks!

-off to work, ill be in the IRC.
