I am hopefully getting hold of an ultra 10 some time soon. I'm not familiar with sun hardware and wondered what the maximum size HDD I can use with Linux on this hardware. Is there any difference in the supported IDE disk size between say Solaris 9 and Linux.

Thanks

I'm able to install 120 GB HDD into my Ultra 10.

I've tried a bunch of different hdds in my ultra 5, and i've had really mixed success getting fdisk to work properly with them. Usually it ends up only seeing 8 or 9 gigs and ignoring the rest.

What I found works very well, is to download the OpenBSD bootable cd image, it's like 5 megs or something tiny. Boot from it, and use the OpenBSD installer, such as it is, to partition the disk the way you want. Then boot from the Gentoo live cd, and you should be able to format and use the existing partitions with no problem.

This is all with the latest version of openboot, in case that matters.

Thanks.

I'm thinking of a secondhand Ultra 10 or Ultra 60. Ideally I would like to add some large IDE disks. I still intend booting off the existing internal SCSI disks in the case of the U60 or the built-in IDE in the case of the U10.
If running linux on one of these, can I use one of the cheap PC style PCI IDE controllers that are supported by the linux x86 kernel? If I can use one of them (ideally in the PCI66 slot), what if any restrictions on hdd size etc will be down to the sun hardware rather than the PCI IDE card?

Thanks for any help.

I install the 120GB HDD out of the standard IDE controller that came with Ultra 10. Unlike DeadlyMuffin, I could get all the 120GB capacity recognized right away provided that we know the head / cylinder / etc numbers. I also had 20 GB HDDs in the past and didn't have problems either.

Note that before I did this, I upgraded the OBP to the latest version. IIRC it's 3.31. I don't know whether 3.25 or earlier would have any success, but in 3.31 it works.

Thanks robbyjo. So with recent OBP I can use 120GB hdd on U10 IDE. I guess this is related to the 137BG limit with many PC BIOS's. I have some <120GB IDE disks that I would like to use, but if I get a U60 then I need to use add an EIDE controller. Are the controllers supported in the x86 kernel available in the linux sparc kernel?

cheers

I have a sneaky fix for this ;)

I have a pair of 40Gig drives in my Ultra 10, boot solaris and let the install program format the disks and write the sun disk label, not reboot and start the gentoo cd and start your install..

wow it sees all the disk ;)

The drawback.. IDE on sun hardware is slow, and I dont mean a litle slow its PAINFULL.

Get a SCSI based system if you need speed or possibly a SUN SCSI controller for the U10.

PC based SCSI cards can be made to work in an Ultra 10, but you cannot boot from them.
