6. Prosbash se terastias xwrhtikothtas diskoys otan den mporei to BIOS

To susthma sto xwro ergasias moy exei IDE disko xwrhtikothtas 1GB. To BIOS mporei na 'dei' mono ta prwta 504 MB toy IDE. (opoy MB shmainei 2**10 bytes, kai oxi 10**6 bytes). Etsi exw ena MS-DOS partition twn 350 MB /dev/hda1 kai to Linux root moy se ena partition 120 MB /dev/hda2.

To MS-DOS den mporouse na egkatasta8ei mono toy swsta otan o diskos htan kainourios. To Novell DOS 7 eixe to idio problhma. Eytyxws gia mena, h IBM jexase na balei thn disketa "OnTrack" sto koyti mazi me to disko. O diskos ypoti8etai oti 8a erxotan mazi me ena proion me thn onomasia "OnTrack Disk Manager." An exete mono MSDOS, mallon 8a prepei na to xrhsimopoihsete.

Gi' ayto to logo eftiaja ena partition table me to fdisk toy Linux. To MSDOS-6.2 arniotan na egkatasta8ei mono toy sto /dev/hda1. Elege kati san ``ayth h ekdosh toy MS-DOS einai gia nees egkatastaseis. O ypologisths sas exei hdh to MS-DOS gia Ayto xreiazetai na promh8eyteite mia pio ananewmenh ekdosh apo ton promh8eyth sas.'' Sthn pragmatikothta, o diskos htan olokainoyrgos.

Ti blakeia! Etsi etreja to fdisk toy Linux kai diegraca to partition 1 apo to table. Ayto ikanopoihse to MS-DOS 6.2 to opoio proxwrhse gia na dhmioyrghsei ena oloidio partition 1 san Ayto poy eixa molis diagracei kai to opoio to eixe egkatasthsei to idio. To MS-DOS 6.2 egrace to diko toy Master Boot Record sto disko, parolayta den mporouse na jekinhsei.

Eytyxws eixa ena pyrhna Slackware se mia disketa (dhmioyrghmeno apo to programma egkatastashs toy Slackware "setup") kai etsi jekinhsa to Linux kai egraca to LILO panw apo to katestrammeno MBR toy MS-DOS. Doulece. Ayto einai to arxeio /etc/lilo.conf poy xrhsimopoihsa:

boot = /dev/hda
map = /lilo-map
delay = 100
ramdisk = 0             # Turns off ramdisk in Slackware kernel
timeout = 100
prompt
disk = /dev/hda         # BIOS only sees first 500 MB.
   bios = 0x80          # specifies the first IDE.
   sectors = 63         # get the numbers from your drive's docs.
   heads = 16
   cylinders = 2100
image = /vmlinuz
  append = "hd=2100,16,63"
  root = /dev/hda2
  label = linux
  read-only
  vga = extended
other = /dev/hda1
  label = msdos
  table = /dev/hda
  loader = /boot/chain.b

Afotoy egkatesthsa ayta ta systhmata, epalh8eysa oti to partition poy periexei ta zImage, boot.b, map, chain.b kai arxeia mhnymatwn mporei na xrhsimopoihsei ena susthma arxeiwn msdos, me thn proupo8esh oti den exei sympiestei o diskos me kapoio programma "stacker" h "doublespace". Etsi 8a mporousa na exw to DOS partition sto /dev/hda1 me 500 MB.

Epishs, ema8a oti to "OnTrack" 8a mporouse na eixe gracei ena partition table poy na arxizei meta apo merikes dekades bytes apo thn arxh toy diskoy, anti gia thn arxh toy, kai pws einai dynaton na "peirajeis" ton odhgo toy Linux gia IDE wste na jeperasei ayto to problhma. Alla h egkatastash 8a htan adunath xwris ton prometaglwttismeno pyrhna Slackware. Telika, h IBM moy esteile mia disketa "OnTrack". Kalesa thn texnikh yposthrijh ths OnTrack. Moy eipan pws to Linux xalase giati den xrhsimopoiei to BIOS. Telika petaja thn disketa toys!
