for IDE drives, better disable 2 switches* for SCSI,

to get e.g. 5.5-7.6 % more speed ( cached & uncached per Win
Tune 98 ) on SiS 530 & ata33, or 2.1-24.1 % on VIA kt266a &
ata133. Win95 does not enable these 2 * ( Disconnect & Sync
data transfer ) by default for IDE drives, but Win98se does ( just
like dblbuff.sys for SCSI is unnecessarily loaded into ram, by
default ) : these 3 designs are ridiculous, how many users have
SCSI hrdwre ( very costly ) ? IDE drives work faster in GUI if
these 2 * are disabled, & faster in DOS ( more free base ram ) if
DoubleBuffer is not loaded, has any1 here gotten similar result ?
I like to see licensed users sue Ms for a partial refund.

If a MVP is here, (i) why must Win98se call a partition a drive
? (ii) why are directories in DOS called folders in GUI ? (iii)
why must fdisk refuse to activate any hdd's boot sector ? (iv)
why fc ( file compare ) can be done only in dos ?
