i told about my experiment - i  boot from 1.44floppy with this ISA card
inserted to check if any conflicts with BIOS extensions and any linux code -
system boots OK ... is it good experiment ? as about memory - when this card
was 'formatted' with 8192 parameter of firmware (to support up to 32Mb
drives) syslinux says 'You have less than 604kb of memory and can have
problems ...' but it was 1.48 syslinux from original lrp package... 1.50
that reqire only >=512kb says nothing... some time later i have 'reformat'
this drive using 2048 parameter of firmware (to support up to 4Mb drives) -
it help to get 'additional' ~200kb of drivespace (from 1.6Mb up to 1.8Mb)
and decrease amount of taken off conventional memory - today even 1.48
syslinux says nothing warnings at time of booting (from floppy when card is
inserted or from card itself but hanging)

what is 'bitrot' ? and where can i found doc1000.c ? can it help to boot
(prevent hanging at 'loading linux..' ) or just help to acess this device
from already started linux (from floppy for example...) ?

i will try to found what is it :|

Thanx for quick reply
