Q: PCIe considered external and bootcamp won't install

Can you power-cycle your MP?

I suggest contacting OWC for this. Their website does say this model supports Bootcamp.

Do you have another disk on which you can test installing Windows?

I don't know if it is possible but can you mirror this disk on a normal HDD disk, then install windows and mirror it back to the original PCIe disk?

It will confuse System Preferences -> Startup Disk if mirroring is used.

Did the OWC contact result in any useful information?

Hey guys..

any conclusion on this matter and topic in this thread.?

Got an Mac Pro 1.1 - 2.66 - 7gb - 7300GT - with a couple of data SSDs (1 running osx 10.6.8 and the other SSD is with windows7-32bit where both drives shows up when booting by holding the key down when chime-sound..wanna give this old fine girl of an Mac pro1.1' an upgrade.

Had in mind:

8x4gb = 32GB (server ram)

GPU 5770

and SSD on the PCIe..

the first two should be pretty straight forward, and partically the ram, seems very cheap like 6US pr 4GB blok (cheap server ram in the right format) and the Apple 5770GPU should be fully supported in mac pro and plug and play with boot-screen. (unsure how noisy the fan is in this GPU?)

But the SSD on the PCIe is pretty expensive, and wanna make sure that i can take advantage of these massive speed in both OSX boot and Windows.

was looking at OWC Mercury Accelsior 240 or HyperX Predator 240 or the Fusion -IO Drive 320..

But it will be huge bummer if theres problem with the EFI32?

Will any of these be able, to use as boot drive for both OSX and Windows, (can Mac Pro 1.1 ewen take windows10.. all in all higher then win7x86??)

THx for any inf and hope its okay that I ask in this thread since it seems to be same topic, about PCIe SSD-possibilities in Mac pro.

You may want to consider SATA SSDs which are comparable and are cheaper than the PCIe versions. They cause less problems during boot. The OWC PCie should support both OS X and Windows, but confirm with OWC.

I suggest staying with W7. From Install Windows 7 and earlier on your Mac using Boot Camp - Apple Support, W7 32-bit is supported. You will run into driver issues on higher Windows versions.

Yep ' its surely quite a hurdle in trying to make sense in what is possible and what aint, and what only relates to +2008 (64) Mac Pro's and wich includes the 32efi and all of this how does it handle to boot in windows and with is only valid past 10.8 when it comes to driver and grahic cards.

An hazzle when trying to modernize an old Mac pro1.1, but then again also close to a decade old.(But Im very fund of it, the materiel, very low noise, the multiple operating-systems on numerous bootdisk)

was planning on putting in a new graphic card, and more ram, and disks on the PCIe.

for ram its seems very straight forward,and very cheap and all server ram with those specs "4GB PC2-5300 DDR2 667MHz 240-Pin DIMM ECC Fully Buffered 1.8V" should work as i reckon. and cost ridicalus 6US pr block, but even if I max out the mac pro1.1. with 32GB I guess its only relative the effect I will receive 10.7.5, and in windows hence the win7-32bit limit, they won't matter.. is it only 2GB that Windows take into account or?

Disks on the PCIe, is it correct that the max, on a mac pro without raid, is about 255mb and limits to the sata2 protocol and the Mac pro 1.1 PCIe x1..

got an couple of SSD-Sata disks in it right now, -an very old Intel 80GB X25-M G2 that cost an arm and a leg back 09 and that specific SSD is laying on top of the two optical drive where there are some space above and also power and its nice and neat put away, and connected thrue a cable to the main board.

The other is a very cheap Kingfast K6 that cost about 45US(incl shipping) purchased an couple of months ago and this one are connected to the first SATA port instead of the 3.5 bracket.

I have pasted the two blackmagic speedtest in 10.7.5 on these two and doubtful have much more horsepower there is to gain, by going thrue the PCIe on  an old Mac pro1.1.

ro1.1..

Any view on this fellow.

I guess its an old dog from Sonnet that are attractive priced (can be optain for 15US+delivery) (retail130US) so quite an attractive price reduction

its an PCIe to sata2.

But looking at the intel X25-G2 that is also sata2 performance.. not sure how much it will be in practice to put such an PCIe board in. but it seems this product is not plug and play and will need an driver, but there is sonnet-driver for // Intel Mac, Windows, PowermacG5.

It states

s it an solution to boost the performance on Mac Pro 1.1 here as of 4Q 2015

The SonetTech product looks pretty nice. Ask them if they have a return policy/window, test it and return it if you are not happy.

Your RAM decision should be independent of the disk decision.
