I'll keep the article in my watchlist and see if any Wikiproject experts can help with this. ← Previous edit		Latest revision as of 23:57, 20 March 2025 edit undo Widefox (talk \| contribs) Autopatrolled, Extended confirmed users, Page movers, IP block exemptions, New page reviewers, Pending changes reviewers, Rollbackers 110,645 edits m →top: bold alt article name per MOS,

Line 1: {{Multiple issues~~\|confusing=August 2008\|unreferenced=August 2008~~\|{{update\|date=September 2014}}}} {{More citations needed\|date=August 2008}} {{confusing\|date=August 2008}} }} A '''System Deployment Image''' (~~aka~~ '''SDI''') is a file format used primarily with [[Microsoft]] products to contain an arbitrary [[disk image]], including boot sector information. == Description == Line 7 ⟶ 10: The SDI file itself is partitioned into the following sections: ; Boot [[Binary large object\|BLOB]] : This contains the actual boot program, STARTROM.COM. This is analogous to the boot sector of a hard disk. ; Load BLOB : This typically contains [[NTLDR]] and is launched by the boot BLOB. ; Part BLOB : This contains the actual boot runtime (i.e. the contents of the disk image including any Operating System [OS] files) and also includes the [[boot.ini]] (used by NTLDR) and ntdetect.com files which should be located within the root directory of the runtime. The size of the runtime cannot exceed 500 MbMB. In addition to this requirement the runtime must also be capable of dealing with the fact that it is booting from a ramdisk. This implies that the runtime must include the "Windows [[RAM Disk]] Driver" component (specified within the boot.ini). ; Disk BLOB : This is flat [[Hard disk drive\|HDD]] image starting with a [[Master boot record\|MBR]]. It is used for hard drive imaging instead of booting. Also only Disk BLOBs can be mounted with Microsoft's utilities. Line 18 ⟶ 21: == SDI features == === SDI driver === SDI files can be mounted as virtual disk drives and assigned a drive letter if an SDI driver is available to allow this. A SDI driver is a type of storage driver and is commonly used with [[Windows XP editions#Embedded editions\|Windows XP Embedded]].
