Re: [Oberon] Re: CF-IDE adapter
Stefan, sw> I remember a problem with an (un- ?)locked media and i think it had something to do with the AtapiBit. It should be easy to fix that in NO. The accordant lines in AosATADisks.Mod should be commented with "CF". Thanks. I'll look at that. I do not understand the point of the lock. Is it the electronic equivalent of the write protect slider on a floppy? Does ATA have the lock for an hdd or just for removable media?

Hi Peter,
I do not understand the point of the lock. Is it the electronic equivalent of the write protect slider on a floppy? For CD-ROMs, it prevents the user from eject the media.
Really I should study the ATA specification ... if it is available. ATA4spec can be found at http://www.myplace.nu/mp3/files/atapi-4_rev18.pdf. It also contains references to some other related specifications. In particular, chapter 6 of http://www.bunfactory.com:8080/shares/datasheets/cfspc2_0.pdf <http://www.bunfactory.com:8080/shares/datasheets/cfspc2_0.pdf> (Compact Flash specification) may be of your interest.

ATAPI-6 - possible more up to date standard. "In order to move beyond the 137 GB limit, a proposal from Maxtor was submitted to the ANSI NCITS T13 Technical Committee and adopted. The new ATA standard, ATA/ATAPI-6, resolves the 137 GB limit by increasing the maximum number of address bits from 28 to 48..." http://www.48bitlba.com/ --- Cheers, SAGE http://sage.h15.ru/
Hi SAGE,
ATAPI-6 - possible more up to date standard. "In order to move beyond the 137 GB limit, a proposal from Maxtor was submitted to the ANSI NCITS T13 Technical Committee and adopted. The new ATA standard, ATA/ATAPI-6, resolves the 137 GB limit by increasing the maximum number of address bits from 28 to 48..." http://www.48bitlba.com/ Yes, I know. There is currently a student implementing ATA6 (incl. 48bit LBA) for Bluebottle. I provided a reference to the older specification because it's the one implemented by the NO ATA driver. The ATA6 specification can be found at www.sata-io.org/docs/serialata10a.pdf, however.
Regards, Sven

Good news! I'v plan to buy new computer with S-ATA HDD :) Runing BB on friend's computer (ASUS P5LD2 motherboard on Intel 945P chipset) has successful. But Partitions.Show~ don't shows HDD attached to S-ATA port... --- Cheers, SAGE http://sage.h15.ru/

There is full specs on http://www.48bitlba.com/ And how about to support in BB 48-bit LBA addressing for huge HDDs (>130Gb)? And how about to create mailing list on not so top-secured server? My postings to the list come to dev/null perhaps... --- Cheers, SAGE http://sage.h15.ru/
