LBA support, drives up to
120 GB possible (so called 28 bit LBA, 137 GB)
new
data structures used
works
only in LBA mode
tested
with 80 GB WD IDE harddrive with 8 MB cache
new
cfdisk
A few 4
GB Coherent partitions created
was
tested in 1.7 GB master(Coherent) + 80 GB slave(Coherent plus
other partitions) configuration
tested
for 2 months and seems rock stable in K6 300 MHZ system, but not
rock stable in Duron 1300 MHZ system yet.Perfect for development
of better versions in both cases.In any case we do not use old
at non-lba driver anymore
80 GB
drive tested on Duron 1300 MHZ system, default setting of BIOS
tested
also in 80GB primary(Linux,Solaris10/9) and 80 GB slave(Coherent
and other), it means You can boot Coherent from slave drive .It
suggests, that one can boot Coherent from primary 80 GB disk
too.
tested
on K6 300 MHZ system, with 8 GB master(Coherent) + 10 GB
slave(Coherent), default setting of BIOS
Does
not require any other changes in 4.2.10 kernel(if I did not
forget something ?)
Should
allow to boot Coherent on any modern PC(even P4)/laptop with
PATA(PCI Express vga is a question!!)
Will it
work with SATA ? Rather not(?). One could try to use SATA/PATA
cable to connect PATA drive to SATA controller.Although old SATA
specification says something about software compatibility with
ATA drivers (?)(perhaps only for 150MB/s SATA ?).
How to
install on laptop without floppy ? Use PC IDE-laptop IDE adapter
and install Coherent on laptop drive connected to PC IDE
interface as a slave. Or use bootit/image/copywipe
partition CD/DVD images created on PC ?
UDMA support .More
about UDMA
Question
: What about using bootit program to boot Coherent in
multiboot configuration ??
Kernel
development environment works fine in the new
system(ddk,idmkcoh,idbld etc) for K6 300 MHZ ,it means one can
switch completely to the new system , the development of kernel
for Duron 1300 MHZ is done at the moment on K6 system, but it
should change soon.
Some
programs have (sometimes fixable) problems in Duron system, but
we do not know if it is caused by the new at driver(?).
Planned
: 48 bit LBA
