Well, why not? Modern home PC mainboards already support RAID (not sure
if they do RAID 5, though) and the CHEAPEST (if you check the per-GB price)
harddisks today are IDE 160 GB ones.
As I see it, RAID 5 is for DATA, not for the o/s. For any modern server
you need minimum of 5 disks (or may as well give up). First two disks
are RAID 1 (mirror) and that's where the o/s goes, the other three (or
more) are for the data and you don't have to worry about booting or
partitions on the RAID5 set.
Most home systems don't have SCSI RAID, they tend to have SATA with
RAID0 or RAID1. I'm not aware of many home systems with RAID5 and
certainly not on SCSI (!), but even if they did there's no point if your
o/s and DATA is on the same array.
Anyway, what are you going to do with 145Gb of striped free disk space
under FreeDOS! My current FreeDOS build fits on 1.44Mb which can then
either be copied to bootable data-stick or bootable CD-ROM.
the BIOS wants you to see, and most BIOSs will only address the first
8Gb. Strangely, Dell latest BIOS's seem to be able to address large SCSI
partitions without drivers, but I don't know how.
By supporting INT13 for the SCSI disks, of course. Basically every SCSI
BIOS can do that, otherwise you could not boot DOS from SCSI at all.
If the BIOS REALLY only supports 8 GB then it is a really bad BIOS,
I just remember many setups in days gone by, where I could only see 8Gb
until I'd loaded the SCSI driver, setting Int13 on/off didn't make any
difference, but actually this may have been a llimitation of the setup
programs I was using at the time (DOS and NT4). FreeDOS certainly is
better. Is there a good way to test what the BIOS can see for SCSI using
FreeDOS? I'm not convinced the numbers in FDISK are an accurate test.
I've seen huge hard disks reported under other o/s, and then when you
try to write above a certain cylinder (maybe 1024) is goes wrong.
