> Linux可以裝在USB HD內

請教一下
這是那一個版本的 Linux ?

鵝只試過Slackware,kernel要patch/重compile過(主要是在init/do_mounts加入retry,讓mount root時USB/USB storage有機會ready),其它distribution鵝不熟,但在load initrd時加入相關module(i.e. scsi,sd,ehci-hcd/uhci/ohci)應該有機會可以吧....

以下是鵝機器上dmesg中相關部份,請服用....

謝謝cmwang網友的幫忙
我也來試試看

不客氣....不過您可能要先確定您的BIOS中boot from USB HD是否work(ex先用win98之類format一個可以開機的partition,然後試著由其boot),免得浪費時間,有些舊BIOS雖有此選項實際上卻沒有作用,另外有些BIOS雖然work,但loader load kernel image的速度卻慢的離譜(i.e.鵝的M/B原先load約1.5MB的kernel image要約20sec),連USB low speed的throughput都不到,後來vendor給了beta BIOS後變成約5sec,算不滿意但可接受的程度----反正load完kernel image後就與BIOS無關了,以鵝的環境kernel boot起來後實測值約25MB/sec----至少比早期3600/4500rpm的HD快多了....

把USB換成1394吧...


不然自己去找那種專門有支援USB開機XP的盒子
所謂有支援USB開機的盒子是有一個自己專門能在安裝XP後能開機的程式

不過有PC的BIOS支援boot from 1394嗎?? BTW,除非OS先天上就支援boot from 1394,不然就算BIOS支援boot from 1394,大概也會遇到跟boot from USB一樣的問題....



您提的thread應該是在討論如何作DOS開機片/可開機的DOS partition出來,而不是如何讓不依靠BIOS的OS(i.e. almost of modern OS except DOS)從BIOS支援的removeable/external storage boot吧....

1. 1394 是M$ 說可以開機的....怎麼開機....呵

2. 那個HP工具可以用在WIN98/ME系列上

叫M$先出個support boot from 1394的BIOS再說吧....



是在98/ME上作DOS開機片/開機partition,還是把98/ME裝在USB HD上而且要能正常boot起來,這兩點是不一樣的....
