Probably. From dmesg on my V100: ebus0 at pci0 dev 7 function 0 "Acer Labs M1533 ISA" rev 0xc3 The Sun V100 is using an AcerLabs (ALi) south-bridge chipset M1535D, that supports ATA-5/UDMA66 which supports CHS 28-bit mode - that is 128 GiB / 137 GB. ALi did a M1535D+ chipset that supported ATA-6/UDMA100 with LBA48 which can address bigger drives. Some BIOS on x86 didnt support this, but there you could use bigger drives with a apropiate driver of the OS. For your V100 I think you just start overwriting the first bytes of the driver if you reach 128 GiB... but I'm not sure. You might test that with dd. > I would very much appreciate to know for sure as I still run >100 of > them.

The V100 is the cheap IDE-version of the SCSI-V120... but I like them for whatever reason too. Their little mainboard inside is somwhat... cute! :) Michael > Thanks, > > Daniel
